You did a thorough job, and it takes time. It is important that each community has its own way of protecting itself from the bad practices of its members, as you have pointed out.

I think that although video verification could help, it would not be decisive. What is really decisive when it comes to recognizing bad practices is the user's performance, hence the importance of communities when monitoring this aspect, for example checking plagiarism, AI content, writing patterns, if the user uses original photos or not, it is important and it marks the user's performance, and it shows us what type of user it is, rather than tightening verification measures.

But it is my personal opinion, as I said, each community reserves the right to verify users in the way they see fit.
