I had viewed rentmassuer ads for years before finally paying to register. I can view ads in a very methodical way, and I'm sure there are plenty of providers who saw me look daily without ever contacting. I had been a member for weeks before I even discovered that some of the providers I had viewed had sent me an in-app message, then called me rude for not responding, and blocked me.
I hadn't even looked at a single message at this point - I just hadn't looked at RM as a place where one sends mails.
