Yesterday I tried to log in to my mail.com account for the first time in a couple months, and I received a message that my account was blocked. I filled out the contact us page and told them that my account was blocked and I don't know why. I got this as a response:
"Dear mail.com Member,
We have forwarded your request to unblock your account to our security department and it was determined that the account in question will remain blocked.
Please note that this is a decision made by our abuse department and we do not have further information we can provide to you.
With kind regards, Your mail.com Support Team"
So my account has essentially been closed with no warning and no explanation whatsoever and apparently there's not a thing I can do about it.
