Evade your ban to post on /meta/.
I actually waited mine out to post just because I honestly did think I was posting too much.
There have been complaints about that previously >>6335 >>6412 Mods are somewhat autonomous so it can be difficult to adhere to standards. Solution is what >>6908

Global bans should still let you post on /meta/ unless you have a /meta/-only ban.
