Airdrop is a reward given to early adopters, either for doing some jobs or for believing the system at it's early stage. Let's assume that some people recieved bitcoin airdrop 10yrs ago, but because the persosn are unable to recieve more bitcoins, then the airdropped bitcoin will be retrieved from them. It doesn't go well to my view.
Speaking about the account in question. It could be that it was dormant for 3 to 4years until 1xbit came and it resurrected and joined the campaign. Since it joined the campaign, most of them spams alot and doesn't have the chances of receiving merits.
I do not send out merit to anyone with legitimate red tag, no matter how quality it is. I believe some persons are together with me on this. So anyone promoting 1xbit has a very slim chance of receiving merits.
