While this is not specified in their Terms, the site chooses to update it's terms of conditions with no warning to users at all. I have no actual source to back this up from but myself and others who have realised this lack of communication. One of the most interesting occurrences recently with the site updating it's Terms of Service (an old copies can be found here: https://archive.vn/https://alanthomsonsim.com/?page_id=621) where it added a phrase on banning users for account sharing (which it had already been doing before the Terms of Service were changed.). Me and those who I asked about this upon realising this ToS change (which seemed to come after a string of bans on this, at the time, unspecified rule as announced on a private Facebook page for the site) hadn't recieved any update from the site about the terms being updated or the ability to accept these new terms. I haven't even received any emails before about any of the ToS changes that may have occured without my knowledge since I signed up to the site (on the 25th of May 2020).
