Hello,
Spamming can mean anything from sending a large amount of emails (the limit is 100 per hour), having a public mailer script, or having a script that allows one to forge email headers like From: and the date header. Your suspension has "zt" in the reason, which is short for zero tolerance, see below for what that signifies.
Unfortunately serious violations of our Terms of Service, which you agreed to upon signup, are coined "Zero Tolerance" meaning that we do not give out second chances. Your suspension falls under this category, which means that your account will remain suspended and you cannot regain any form of access to your account, its databases, and its files per sections 6 and 8 of our Terms of Service. Your account will be automatically deleted in 14 days' time, perhaps longer.
