There is a great coincidence in the time each account went offline and also those accounts seems from a particular country. Could it be that the time range is a period they go to bed in their country?
My major interest is not whether the accounts are controlled by one, but none of the accounts has gotten to full member rank, despite registering as far back as 2017, 2018 etc.
I believe that the chances of one person controlling 14 accounts is rare, because there won't be quality in the post, unless for works as dumping links in the thread like bounty hunters do.
A few days ago. This "notscam" guy asked me for my telegram, and I talked with him. He added me on a telegram group where some inactive Bitcointalk account was up for sale. Most of them were Full Member rank accounts. I didn't have enough time to investigate. It's unethical to pretend to be a buyer and expose those accounts. Because Later, the community will say you are a potential account buyer. <>> After I had managed to investigate a little bit, I saw "notscam" guy delete his telegram account so I didn't bother to contact him anymore since my last two investigations were questioned.
I saw where notscam asked you for a telegram username, I thought you both would form a formidable force to expose cheaters, not knowing that notscam will turn scam. Anyways, both of you are alts and could decide to do anything with your alts while keeping your main accounts safe.
