Most of the bots on Lemmy have been well meaning, but ultimately annoying.

The issue is there isn’t really a lot of traffic on Lemmy. And from the people that are here a lot of them are lurkers, just consuming, maybe upvoting once in a while, but that’s it. This leads bots that reply to a lot of comments/posts to become a large part of the traffic and thus the experience for the users. There isn’t enough for the bots to get lost in the noise. This also leads to the user experiencing the feeling of only interacting with bots, instead of other people. Most people commenting are looking for people interaction and get annoyed when they think they have such an interaction only for it to be a bot.

Lemmy is also very focused of an audience at the moment, which leads to bots not really being necessary. People here are usually very tech savvy and know how to do most of the things. A bot that explains how to do things people already know how to do comes across as unneeded.
