Is the female moderator sinful if she shares the link of one of the members with other female moderators in a private women's forum, due to suspicion that she is a man or the same member with a new ID, for the purpose of monitoring and verifying her compliance with the rules?

Women must be warned about the dangers of the internet, for women are targeted for corruption, and they must be careful when dealing with others. If there is a suspicion based on strong evidence that the interlocutor is a man or an unsuitable woman, the forum moderators must be informed, as this is a necessary precaution and a religious responsibility. However, if the suspicions are weak, it is not permissible to accuse people based on ill-conjecture, as Allah Almighty says: (O YOU WHO HAVE BELIEVED, AVOID MUCH [NEGATIVE] ASSUMPTION. INDEED, SOME ASSUMPTION IS SİN) and the Messenger of Allah, peace and blessings be upon him, said: (Beware of suspicion, for suspicion is the falsest of speech).
