This is why you got silenced not because you asked about the raffle. You posted on my wall asking to be added to a third party gc which is against TOU.
Hey everyone! We've announced the Grand Prize winners! https://forum.partyinmydorm.com/threads/winners-of-the-masquerade-raffle-🎭.145065/#post-5231161 If you weren't a grand prize winner, you still have a chance to win plenty of other prizes! These are all starting to be given out now so you should see these appear in the next few hours. Thanks everyone for participating!
Pms, gifts, and club chat are all considered private channels. Campus chat, pub chat and walls are public channels and you can be silenced for violations in those.
If you're not sure what is or is not silenceable you can find the latest updated silencing policy here
