My thoughts on this is pretty much voiced by some of the others.
For instance, there was a tool that could be used to repost things from a reddit user page. I've warned (and the dev have added the warning to the repo itself) that the tool can cause one to be banned. Now the only way I can see that working without inciting a ban is if the tool was triggered by a command, and only took one link at a time. Assuming the mods already gave permission. Something like the wiki bot I've seen over on reddit that posted the overview of a wiki link. However, I would rather be able to trigger it with a !wiki or something to that effect.
The only exception I would take with this is with an automod that reminds users to include specific things in their posts...but I'm also meh about this. If people post without reading the sidebar, they're probably not going to bother coming back and reading a comment. This issue would be better solved through other means (a reminder of the community rules in the New Post page, after choosing a community).
The bots 100% need to have the bot tag on. No bots impersonating as people, please.
That's my 2¢ for now.
