EBNcraft was not subtle about wanting to speak with the owner about a deal for joining up servers, was quite pushy, posted a text wall with their website link, and privately asked me to join their server.
Now, I don't think this is explicitly in the rules, but it sure is rude. Originally, I entertained them and said they should message a mod and sign up in the meantime (even tried to give them some baked potatoes to start their journey), but they don't seem to have any interest in signing up for the website or being productive on the server, and mentioned getting banned from 3-4 servers a day for advertising.
They then proceeded to insult me when I pointed out that what they were doing was pushy and kind of rude when they PMed me to join their server, in what I thought was a civil way--being subtle wasn't working. I blocked them after their insults started getting sexual.
There were no mods online at the time (~12pm PST).
