"funny" bots
Like haiku bot, "all words are in alphabetical order", And character bots (think kenobi or vader bots in sw subs) that add nothing of value to the actual discussion.
reddit sings / ask oija
Posting song lyrics line by line is kinda fun,
But it also doesn't add anything of value.
this is the way / catchphrase spam
Also void of any actual discussion.
Just blind repetition.
negative subs
This one is probably controversial but, Stuff like gamingcirclejerk, nicegirls/guys, gamingcirclejerk, enoughmuskspam.
When you actually like the subject you just get the worst parts of it / its community rubbed in your face,
If you dislike it, its just the worsts part of a thing you hate hilghted daily pissing you off.
And imo if these subs lack an influx of "natural content", it becomes zealous, seething and unfair.
Also the peak of irony always was, whenever enoughmuskspam was the only musk related post on r/all
