Yep they're buying multiple phones. I personally know one creator who bought 3 iPhones just for tiktok. She is not even top creator in onlyfans. But 40 is bit much. She might be using mobile proxies as well. And one can create multiple accounts in tiktok but they get ban early.
Well i tried selling one expired domain to real estate company in India a year ago. They didn't replied.
I was little scared, so i let it expired.
It's almost 4-6 months. It was available to register again. But they didn't register it. Maybe they don't care
