True, problems will arise when they are proven to abuse their account to join the same campaign. The explanation here is pretty self-explanatory because I've never come across a campaign or bounty that allows multiple accounts. So when they are found guilty then the tag is the consequence they will accept.

I very rarely expose newbie who joining the same campaign, meanwhile I have nothing against others wanting to do so. The problem is, this case looks like it will never be resolved so I can honestly think that eventually the thread - Known Alts of any-one - A User Generated List Mk IV (2022 Q3) [MODERATED] - will archive hundreds of dozen newbie per year. There are very few newbie who will make excuses and try to explain what the problem is, while thousands of others will create new accounts to do the same job.
