Your account still is wearing a signature, so it's not permanently banned.
Given the recent password reset and email change, together with the feedback by numanoid, I assume it's been hacked and has been locked as a security precaution.
If the hacker changed the email, however, you will have to restore access via Cyrus or theymos, and with a signed message, as you are already attempting.
I keep to PM Cyrus every day
So I a bit worries whether Cyrus or theymos can disable message from newbie or I wrong if I'm bump PM every day?
Theymos and Cyrus have not blocked PMs from newbies (or from you), if they would have, you would get an error message when attempting to send them one.
However, sending Cyrus daily PMs is a bit over the top.
Sending a signed message to recover your account once, and then resending it a bit later (maybe two weeks later) is sufficient, you do not have to bomb them with daily PMs, they get enough messages as it is.
Send one PM to Cyrus. If Cyrus doesn't respond after two weeks, you can try sending a PM to me instead.
Keywords there being one PM and two weeks.
