Moderation is all over the place at reddit. Some subs will thank you for flagging bots, some have a zero tolerance policy for "accusations of this kind". Some subs will flag your comments and tell you to clean them up if the content violates community guidelines, others will hand out permabans on the first infraction. Then you have the subs that are at a constant state of cold war with each other and simply ban anyone who ever posted on one of the opposing subs.
