Nope, they accept any IM format. AIM/MSN/Yahoo/etc. It's been in their FAQ for ages. It's down at the moment due to DDoS. Hopefully it will be back up asap. A bunch of the mods/admins hang around in #geekissues on EFnet so go ask them for more details. I personally don't see a use for msnbash. Oh, btw, the two quotes on that image are just not funny. :/
