In my opinion, there are small violations that can be overlooked when moving to another forum. Most members come to the forum at the beginning and do not have much experience with the rules of the forum, so they commit some violations. With time, they improve and realize their mistakes, and they may need a new beginning free of mistakes, and this can achieve On it in the new forum.
As for the members who have been proven to deceive and defraud others and steal their money, such people cannot be overlooked or given the opportunity to start a new beginning, because the fraudster who is accustomed to fraud will not change his behavior, but rather is looking for a new opportunity to defraud a new victim.
