Do you truly not find any of them useful? There are a great many awful bots out there that range from mildly annoying to down right disruptive, but some of them can be quite useful. Looking at examples from Reddit, I think the wiki summarizer bot, RemindMe bot and video archiving bots were all pretty useful for example. I’ve also found bots on card game communities that reply to something like ![NameOfCard] with a description of the card, which is absolutely helpful.
