kemono.su, coomer.su

Previous relevant issue: #18275

(Hopefully nobody will be rude in this one…)

Did some testing to see if the current whitelist is sufficient. Caught a few things that will need tweaking.

1. There's an endpoint for flagging posts that needs whitelisting. URLs are of the following form:
   • https://{domain}/api/v1/{service_name}/user/{user_id}/post/{post_id}/flag
2. User IDs can apparently contain letters and underscores (potentially more), not just purely numbers.
   • e.g. https://coomer.su/onlyfans/user/sweetiefox_of
   • These may also contain uppercase characters: https://kemono.su/dlsite/user/RG13809

Where:

• domain is either coomer.su or kemono.su (they seem to have the exact same API and codebase)
• service_name is one of the various services archived by the site, which appear to be all [a-z] but seem conceivably like they could contain numbers and punctuation if the name of an archived service does
• user_id is the identifier of a given user, which depends on the archived service and can probably be arbitrary, but seems like it is mostly made up of either purely numeric IDs or username strings
• post_id is the identifier for a given post, and is likely only ever going to be numeric

In summary:

• Rules currently break the flagging endpoint; an entry in the whitelist is needed to correct this
• Rules for other endpoints that assumed usernames would be purely numeric need to accept letters (both uppercase and lowercase) and underscores, in addition to numbers
  • This varies per-service and could be made more restrictive by figuring out the rules for each service individually… but this seems not worth it.

Should be noted: I reviewed the site, and it looks like the operator has removed all tracking from their site in response to previous filter changes. Visiting webpages under a variety of circumstances (logged in, logged out, incognito, adblock on, adblock off, etc.) show no POST or PATCH requests to tracking endpoints. Checking the site's forum, it looks like users have assumed the recent functionality regressions caused by this list were due to the operator breaking the site themselves, and the feedback has been… honestly rather horrible. Lots of abuse of the site operator in there.

Not sure how this list prefers to handle such scenarios, but I suspect the site operator realized that the rule evasion arms race does not end favourably for them, and have decided to drop tracking entirely. I'm unsure how we prefer to handle such situations, but we could avoid a good chunk of maintenance burden and user-side breakage potential by removing the filter rules for the site, given the change. I would volunteer to keep an eye on the site for a while to be sure it stays that way—it's not convenient for me, but I think that's the best outcome for everyone collectively. Maybe I'm not jaded enough yet, but there you go.

Anyway! Hope that's helpful.

I added

@@/^https:\/\/coomer\.su\/api\/v1\/(?:fansly|onlyfans)\/user\/[a-z]+\/post\/[0-9a-zA-Z]+\/flag$/$xhr,1p,match-case,method=post
@@/^https:\/\/kemono\.su\/api\/v1\/(?:afdian|boosty|discord|dlsite|fan(?:box|tia)|gumroad|onlyfans|patreon|subscribestar)\/user\/\d+\/post\/[0-9a-zA-Z]+\/flag$/$xhr,1p,match-case,method=post

and based on your description I don't see why they don't work except for another point of user ID which I will fix.

I'm also ready to relax {service_name} part, but if you can provide the full list of them this is the best. Not saying waste your time, but want to confirm at least one example not covered by the current rules before relaxing.
