The assumption would be they don't want anyone seeing it now. Which would then be further proof the whole scheme is a fraud.
I dont think so.
8-chan appears to have a dedicated page to which only Q can post. I have been looking at it over the last several days and I did not remember seeing anything about speaking Russian.
The link on this thread is to something called GITHUB. It appears that someone has been pasting The Q posts from 8chsn to it and adding extra comments that were not included in the original..
