You could actually be correct, but the way you stated it so emphatically could arise some questions. Forum is not against airdrops but maybe they restricted it from that particular board. If OP can find a way to share his knowledge and the airdrop link without going against any forum law. This could be fine.
Secondly, airdrops were popular in the early days of cryptocurrency. I don't know people are still seriously into it.

Op, sorry. Theymos is not gonna create any sub board where people will spam with airdrop links and tasks that will definitely lead to scam.
