Being reported doesn't necessarily mean that an account will get banned. Staff will look at account history and content before making any decision and generally starts with warnings, escalates to mutes of various lengths, then account bans. Banning can happen more quickly for more extreme instances .
If you block someone, they should not be able to direct message you or comment on topics you start. They also should not be able to chat in Live Chess. The site wide chat is not impacted, as far as I'm aware, but you can hide/disable the chat from any member and it will only show up under inactive.
That said, please do not publicly report members.

Are you absolutely sure the member is on your block list and it's not a similar name?
