That is why I created this thread and keep answering from time to time to bump it to the top and make again visible for a while to let another couple of newbies on Bitcintalk be able to read it.
I assume that more experienced members from this community know already about this and never share their documents with bounty or airdrops, especially full scans and this type of documents.

Luckily, lately, there are not so many lucrative airdrops and bounties are ending too slowly. Only a couple of high-quality campaigns are active and managed by good CMs.

I think threads like this changed the awareness of people and today it will be a lot harder for scammers to convince them to share KYC documents.
In the time of Hyip and FOMO in 2017, this was like a plague, but everything is slowly evolving and the cryptocurrencies world is changing.
For better I hope  .
