Although the user didn't contribute anything to the forum, but I quite respect he haven't cheat any campaign until now... or he's smart enough to leave his trace?
Chances are that he only hasn't been caught yet as it doesn't make sense at all to join bounty campaign with 1 account only since everyone else is cheating.
Exactly my thinking. It's worth noting that he created his account in 2019, which was well after the peak of ICOs and shitcoin bounty campaigns. It's possible that he hasn't yet been caught cheating, probably because this may not be his first account and he has likely learned to be careful (perhaps from his own past mistakes). In cases like this, I typically examine their posting patterns. As we can see, he usually spend around half an hour to an hour on the forum each day. Therefore, it's reasonable to assume that he could easily manage dozens of such accounts simultaneously.
In my view, this is the only explanation that could justify the amount of time they are investing in this activity. It is essentially unprofitable to engage in these campaigns with just one account, given the current payout rates and the low probability of any individual campaign generating a significant profit.
