Can't post on bitcointalk.org
It's likely that your account has "units of evil" which require you to pay money to remove them. Bitcoin, the program used to accept these payments, is down. See also https://bitcointalk.org/index.php?topic=953005.msg10434122#msg10434122

You also have restrictions on your account due to being a new user. See Why can&#39;t I participate on bitcointalk.org?
