Dimecoin arguably got giveaways banned (or was the final straw) due to the daily influx of posts. Monero dwarfs anything dimecoin did. it might not give stuff away, but it is noisy and irritating and the threads are mostly ridiculous.
Maybe have a rule where a coin in alts gets to a certain limit, and then gets its own dedicated thread. It takes up too much room.
*Edit: I just counted 17 dedicated threads on the first page Altcoin discussion.
Is that all it takes to get a coin banned? A couple of trolls posting spam threads?
Perhaps if I create some dummy accounts and start a bunch of threads about you I can get you banned
