Please, what could be the cause of the ban?

I posted a topic about how a post can be merited and I was banned the following day. All my posts were deleted. I wrote from my head with the knowledge I got about bitcoin and other cryptocurrencies.

I will be glad if my posts can be revealed, it was all deleted after the ban.

My posted were deleted at ones and no email message about the deleted posts.
