Dreamy, We do not mind at all if you play on other servers. No need to delete any ips. We understand there are many servers to choose from, and they all have different environments and play styles and all serve different purposes.
Our issue is with those other servers being advertised on this server, or by any Famcraft related means. We really strive to keep this server clean, safe and family friendly. We don't control what happens on other servers, so we do not want players here being directed to other places. Plus, we like it when players play here.
If you need to tell someone something about another server, we just ask that you use your own skype, email, text, phone or other non-Famcraft form of communication. Most servers will have a similar rule. We always like to remind other players to please not mention/discuss/advertise Famcraft on other servers, as well. We know they like to keep their players too.
I will pardon you now, but please do not mention other servers here in the future. Thank you.
