They still happen(airdrops) and I reckon some people still make profit out of it hence why it still happens in the first place. It being profitable is another thing though. I haven't done any since before and even till now still don't think it'd be worth the time and effort spent. I'd much rather just grow my skills instead.

You certainly won't see much here though. I'd say go to X and some big crypto discord groups. They usually have a lot of news for projects with big airdrops.
