how can this be vulnerable against abuse and can you reopen the topic, please?
Very simple proof: if groups of people want to abuse the system, then its obviously very easy to see who and how many reports have they submitted - if certain groups with the same exact names submit too many reports and the victims start to complain, then the abusers will get a permanent ban themselves instead? But who would want a permanent ban for this kind of thing? Absolutely noone, which means that it will work flawlessly.
