# Contents
The uBlock, adBlock like filters you will find inside this repository
will in some degree be a supportive to the more common know filters like
[EasyList][EasyList] or [AdGuard][AdGuard].

## About
Some important notes is this project started as a private project,
however as the time how parsed by, it looks like other users are using
one or more of our rules and filter, just as we are including 3rd party
filters.

This means the precision in the filtering rules might not be as sharp as
they could have been if this have been a major part of my portfolio,but 
this is purely a side project.


## Disclaimer
I can't guarantee these filers won't cause problems. If you found
problems, [report][issues] it by filling in all the mandatory items in
Issue template; otherwise reports can be ignored. Anyone who uses any of
my filters/codes shall be deemed to have agreed that I have no

# Writing filters

## File structure

| File naming                  | Supported filter types                                                                                                                                                                                                                                          |

| `_domain.`                   | These filter lists is to ad rules based on a domain specific level. ***IF / WHEN*** a rules is covering more than one domain, you should add it to the corresponding `_rule` filters                                                                            |
| `_rule`                      | The place for rules covering more than one domain.                                                                                                                                                                                                              |
| `adult_*.blacklist`          | This is as the filename indicating the place to add NSFW ONLY contents *AND* only if it do not match any other filter(s)                                                                                                                                        |
| `adware_*.blacklist`         | Let take a guess, any promotional contents this is external as internal ads                                                                                                                                                                                     |
| `annoyance_*.blacklist`      | Any kind of rules which did not fit into any other filter(s) and which does not as such brakes the functionality of the site.                                                                                                                                   |
| `anti_social_*.blacklist`    | filters that can help preventing building any kind of tracking links to any spyware domain like google, yandex, facebook, TikTok, Reddit, Telegram or similar (anti-)"social" and anti-democracy places.                                                        |
| `anti_whitelist_*.blacklist` | Found a rules elsewhere your would like to encounter, this is the filters for it.                                                                                                                                                                               |
| `cookie_*.blacklist`         | Everything preventing cookies being set, where not needed or used for any sorts of tracking/spying/logging :cookie: (1st & 3rd party)                                                                                                                           |
| `noise.txt`                  | :warning: **_WARNING_**! The following filter, WILL bring interruption to sites functionality. These rules are to clean up sites by removing all the unnecessary noise, bit like @yourduskquibbles webannoyances, but breaking things doesn't matter **AT ALL** |
| `spyware_*.blacklist`        | Filter preventing any kind of tracking, spying and alike. If you have to ask, you need to read [SpyWare Wiki](https://0xacab.org/my-privacy-dns/matrix/-/wikis/Categories/Spyware/SpyWare)                                                                      |
| `whitelist_*.whitelist`      | Probably not very used... But it can come in handy sometimes protecting something to keep is spinning....                                                                                                                                                       |


### Sorting filters
We are sorting the rules based on the second level domain in the `_domain.`
filters. In the `_rule` we sort based on the letter/number `[a-zA-Z0-9]`
disregarding the actual filter first are present at the 3rd argument.


#### Example
In this rules we like to hide the `.modal-backdrop` but to actually succeed
with this, will need some more arguments.

```css
##.show.fade.modal-backdrop
```

This should be sorted by the first `s`

## Filter Inclusion - Exclusions
We will only in sevier cases include any rules that could/can be blocked
by a DNS related firewall like DNS RPZ.

**IF** a rules is included, this will be to support the tor-browser where
any local firewall rule is bypassed.


## Writing filter guides
Howto? block whitelisted spyware: (~~`https://github.com/easylist/easylist/issues/4529`~~
SpyWare infected domain)

`$` always needs to exist, if you're going to use a modifier.  
`,` are used to separate multiple modifier.

Example (single modifier): `$script`  
Example (multiple modifiers): `$document,frame,script,stylesheet`


## Counter other's rules
You can't use `badfilter` modifiers for cosmetic rules.

For example, `#@#.ads` can't be disabled with `#@#.ads$badfilter`

Instead, you need to re-activate the CSS rule with a new blocking
rule, which goes under the whitelisting radar (so-to-speak).

To override `#@#.ads`, something like `##[class="ads"]`, `##[class^="ads"]`
or `##[class*="ads"]` is needed. The (`^` = begins with / `*` = contains)
will work, since `#@#.ads` only disables/whitelists `##.ads.`

* `$badfilter`: Deactivates a resource-blocking entry, even if it is
  present in another list.
* `$important`: Makes a resource-blocking entry take precedence over
  another whitelisting entry.
* `$redirect`: Redirects resources to a neutered version that has been 
  embedded in those extensions. Possible options are listed in
  [this file][redirect-engine]
  (AdGuard has a [slightly smaller selection][slightly_smaller_selection]).
* `$empty`: Results in a fake empty page being loaded, instead of an 
  error page.

### badfilter example
If the original rule was like

```css
@@/advertise.js$script,domain=example.com|xyz.com
```

Then

```css
@@/advertise.js$script,domain=example.com,badfilter
```

is a valid filter, it disables the whitelisted rule only on `example.com`.
