everything i say on a topic gets flagged no matter what
the posts you were referring to are spam or necroposting. necroposting is posting to a topic long after its last post, and not saying anything but "ok" "yes" "+1" which is not meaningful or useful to the topic, and unnecessarily notifies the people in it.
Maybe random people false flagging? I literally have no clue since all i do on the forums is just read.
Edit: helicoptur just explained what was happening.
