The SQL way
https://lemmyverse.link/lemmy.ca/post/40761824, thank you to @shadow@lemmy.ca! Note this does not work with regex patterns.
The slur filter way
(.*(\n)*Hi.*[nN]icole.*[fF]ediverse [cC]hick(.|\n)*) Is what we are using on dbzer0 right now. It previews all of nicole’s messages as just “removed”.
Why such hacky fixes? Well truth is, due to lemmy’s subpar filtering we really can’t do much about this currently. At most these just repel from the potential harm of nicole’s messages.
@db0@lemmy.dbzer0.com has opened these two issues:
Regex probably isn’t the best use case here, as the spammer can pretty easily change the format. They’re already trying to do so with random spaces and stuff.
A better option would be to have the option to disable DMs from instances that do not require email/sign on approval requirements. Not sure if that’s already a feature, but I can’t imagine it would be a fun one to implement.
Not possible for lemmy, and it would be hacky to implement for us (db0 doesn’t really like the SQL version) so we’re sticking to the slur filter for now unfortunately. I’ve adapted it, and it’s very extreme; but should work for all types of cases for nicole.
