I couldn't help checking your profile after your post on the newsfeed about Rui, and I have to say he very much had reason to neg-rep you. You are possibly the most offensive person I have ever seen on Hive. Writing "f*ck you", telling people they are a "piece of sh*t" and such on other people's profiles is literally considered flaming and goes against Hive's rules. I don't mean to sound disrespectful, but if anyone deserved to get banned, it should've been you.
PS: You are welcome to respond to this in an attempt to redeem yourself from your actions (after all, you may have had reasons to act as you did, and if you do indeed have, I deeply apologize), but if you do so in an offensive manner, I won't hesitate to report you.
