You know, for a long time, there were sites that paid pretty decent money for completing certain registrations, surveys, and other tasks. But according to the site's requirements, it was believed that it was necessary to be a unique individual. That is, you must have everything different, including an IP address, browser, device, and, of course, address and name. If all conditions were met, the site paid for each new person on a new device. But this was quite difficult to implement since the site saw all the slightest trackers, including the computer processor and video cards. Nevertheless, people managed to engage in multi-accounts. The browser anti-detect was created for similar purposes, but at that time it cost good money.

I wrote all this as an example of what you are asking about today. Multi-accounts are allowed on the forum, and only detectives who find connections through social networks, transactions, and similar matches are involved in catching them.

I agree that not a single experienced cheater will come and admit how many accounts he has. As long as the forum allows it, you can create hundreds of alternative accounts.

But if the ban is at the hardware level, so that registration is prohibited by matching trackers, the number of accounts will be reduced to one account per device. It's simple. But here we must choose either freedom or uniqueness.
