It is not clear to me that you have understood, precisely what I am saying is that these are all alts of the same. Polo7.
Just because a scammer is stupid does not make him less of a scammer. It makes it less likely that people will fall for it. But even scammers more sophisticated than this one play with the big numbers, they know that they will only be able to scam a very few people but only with those few will it be profitable for them. There is always someone clueless or naive that can fall for it.
I've understood that Polo7 is an alt of the accounts mentioned earlier; I didn't comment on it because the main account has been inactive for years; his alts, however, aren't. Unfortunately, even though they've been tagged and reported multiple times, their posts still remain intact, and so are their accounts. Since it's evident that they're multiaccounting and using their accounts to spam the forum, they should have been banned a long time ago. I acknowledge that they're still scammers, even though no one will hopefully fall victim to their stupidity, and they should be treated as malicious users. I'm not considering it unimportant just because they won't successfully scam anyone.
