recently i have run my blog on wordoress. but it is not easy, and many problems occur. and twice my account was suspended. I wna to know besides the pingbacks, any other factors may lead to the suspend? Thanks in advance for any sharing!
I'm not an expert on this, but the main things to look for are illegal/spam content on the blog itself or rude/spam commenting on other posts. Do you think either of those could have caused your issue? You could also try emailing the wordpress staff and asking for a cause -- you might not get a reply, but it can't hurt.
If you're running your blog on wordpress.com, then violating their TOS would be a valid reason for you getting banned. Wordpress.com does not appreciate splogs, so if yours was one, you know the reason why you were suspended.
Remember one thing, Wordpress.com doesn't allow you to put ads in your blog. If you show ads, you will get deleted.
I think you're using wordpress on your own host. Maybe you've intalled a twitter plugin which had bugs
Keep your blog and plugins upgraded. Check all themes for any malicious code inserts. Also clean out database, change passwords to keep your blog protected. And do look on access logs for anything suspicious. And do check your page/sql query usage. These might be some reasons that your webhost is suspending your blog.
