Hi David,
I recently (last week) got control over that site, and purged the plugins site of a great deal of spam, but this was long after your initial complaint that your account had been blocked (April). So I don't know why your account was blocked to begin with, but I see that there are no plugins/posts by the account (
http://plugins.jquery.com/users/zazar/track) at the moment. Did you already post any plugins already that have been lost? If so, I'm sorry for the inconvenience.
I have unblocked your account, so please go ahead and (re-)post your plugins, if you like. I do not know whether or not the following applies to you or not, so take it with a grain of salt, but do note, that we are no longer tolerating the posting of plugins on pay-to-download sites with affiliate marketing links.
Thanks and sorry for the long turnaround time...
