It seems like this is often done by scammers, they have certain goals for this. Hemm, this is really annoying because there are more and more of them. Not just 3 but more than that, and many more. At first I also felt like I had never bought these tokens, but it turns out they are increasing over time. And this is annoying because they are just shit tokens. Not only that, actually it doesn't matter and just leave it, as long as you don't click or follow the directions for further suspicious things. but unfortunately, it becomes like dirtying wallets. Because there are more shit tokens like that than the real coins we have. But what else, you can't remove all of that from your wallet. That's the risk when we share our wallets publicly, usually when we enter our wallet address when participating in airdrops or bounties which can be seen publicly by everyone.
