Advertisement on Facebook on the topic of the blockbuster. How to be?

Hello everyone, my company is engaged in holding conferences on the technology of implementing Blockchain in various areas. There are business pages on Facebook that have advertised about these conferences. At the moment (for the whole month) we were blocked on facebook because of the ban on advertising ISO, bitcoin, and they do not respond to my messages, I already wrote them. Silence in return. Tried to different ways of advertising - do not write in the announcement about the conference, only the picture with the inscription about the conference blockchain, all the same we were blocked. Someone knows how to bypass their system and continue advertising?

P.S. We start advertising in many places and in different social networks, but for a month of disabled facebook very much felt the damage. Facebook gave a lot of people who got on the site.
