Thanks Mario - indeed it seems to be a bit random, maybe there was an update recently- on Hungarian Wikipedia as an anon I today see an edit button but then it tells me I am blocked (it doesn't give any real explanations, but at least the link to contact the stewards goes directly to the contact form) , on English Wikipedia when logged out I get the edit button and block message, whereas if I am logged in I get a locked pencil edit button and a nightmare of a block message: it is a wall of text that asks me to put something on my talk page, and then instead of linking to my talk page, it links to a help page that explains what talk pages are... Or alternatively it leads to an unblock request system, but also asks for my IP address that I should get by going to an other wikipedia page that should load my IP address, but in fact doesn't neither logged in or out...
