Seriously, if that's the case and they really need to enforce a limit, they need to allow the option to at least remove unwanted users from the list so you can keep those you care most about. And I don't mean "Block user" if that even works the same way...
I guess that when "Start Conversation" equals to "Get yourself added to another's contact list, even if you don't say anything to them", then they really
need to enforce a limit.
There is absolutely no way to remove anyone from your contacts list - ironic, isn't it? Random people can add themselves, but you have no control over who is, and stays in your list. But hey, why would you want/need it? GOG's design choice is taking care of things!
And "Block User" does not remove them from one's contact list either, they're just placed at the very bottom of it, until kicked off by someone else adding themselves at the top.
As I said, it's a terribly poor design choice; it boggles the mind that someone had this brilliant
idea, more so that it got the seal of approval.
