Account blocked for suspected spam

I am unable to log in to my WordPress site, attempt to log in returns “ERROR: Your account has been marked as a spammer” and I don’t understand about this spamming.

I installed Unique Article Wizard WP Plugin and received posts to my blog. I edited and re-posted one of the articles in accordance with the rule and my account got marked for spamming. Is Unique Article Wizard re-posting not approved by WordPress?
