Actually you don't have to focus yourself to prove if any account is an alts, you just have to give them time those with the mindset of cheating the forum will let their guard down eventually and then you can easily identify them as alts and if they have misuse any of the privilege of the forum in their process of been on the forum, necessary action then has to be taken.
Golden words that are sure to be confirmed by experience. There are a lot of newbies who try to hide their connections, cultivate their accounts for quite a long time, but subsequently, they often make some small mistakes, and, they all end up with tags if they do not go into a ban.
Today I see a similar bunch of accounts growing rapidly with merit. These accounts are good at writing, but there are overlaps in writing style. Therefore, I have already written more than once that alternative accounts are not prohibited, the transfer of merits to each other is prohibited, and, well, banal participation in the same companies. Time will judge whether they are honest or not.
That's your point of view. But there are newbies who don't intentionally, but unintentionally break the rules of the forum like copying content from the internet or this forum only and pasting it here in the greed of gaining merits and then, they get banned, they spam and get tagged for the same (we researched and saw that many spammers were getting tagged when one of the most active users of this forum "Lauda" was here, but now spammers do not get tagged but either warned or are not enrolled in any campaigns here). There are the type of newbies here who also try to learn from their mistakes, and take lessons from old accounts here who are knowledgeable enough to teach something that could be advantageous to these newbies.
Here is a shining representative of a beginner who is far from a beginner. I do not believe that with the registration April 26, 2021, one can be well aware of the user "Lauda"
When I was a beginner, I found out about it after quite a long time.
