Thank you for your advice. I've already blocked the domain of the first few profiles, but still there are some postings popping up on my timeline, that are on other servers, but always try to lure me to the domain I've already blocked.
Why is that? How do they manage to sneak onto my timeline, without any hashtags involved and without me following them?
