That's exactly what likely happened. Strainly seem have a tight policy. It may be their way of keeping the platform safe. Someone can ban you IP address if it's associated with someone with a bad reputation. try to email them or contact them via their IGYeah, I wonder whats up with that?
Ive read that oftentimes we get a used, old IP address, and it has had problems in the past, and when it gets reassigned to another person, they get screwed.
