The accounts currently participating in airdrops, bounties, and giveaways are mostly Newbies. Due to their lack of experience and impatience, they may participate in many of these free opportunities within a short period without doing proper research, making them easy targets for phishing links. With the increasing popularity of Telegram mini-games and their promises of free rewards and TGE, scammers will undoubtedly intensify their efforts to deceive beginners. Therefore, our positive role is to expose these scammers and report their activities and schemes to hinder their progress.
The good thing is that the culprit in question has been banned.
I'm glad to hear that. Thank you all for your contributions. I think I can lock the topic now, as the scammer has been punished, and his posts have been deleted. However, I will still file a report to the registrar to take down the domains as well.
