Now I get it Mahith1708 thanks a lot, the symbol for unblock are on my Profile!
That is a very good point, but this person like more talking than listening. I can tell him before that I will block him indeed, and then unblock.
Is unblock the same button then, width another symbol?
As teamleader I feel that I get to many messages from a specific player, just under during one kind of tournaments, I can deal width in general, but not just in Lichess-Liga. Is a block permanent?
