I just got a comment on my post:

This is my own work, I think it was commented on because I used a quote. Despite your disclaimer it looks like an accusation when you comment and many people take it as such.
Perhaps a bot is not the best method for this and it should be a bot combined with a manual review, amending comments when the bot gets it wrong.
