Well, I figured out who deleted all those posts and why. In local threads like yours, there should not be any announcements of specific alternative cryptocurrencies, posts with airdrops and subscription campaigns. Since you don't (yet) have a separate section for altcoins, bitcoin and other cryptocurrencies should be talking about here (discussion only).

Here are links to the deleted posts, there should be no such posts.

P.S. This is not my whim, these are the rules for local threads.
