Everyday I get into my WordPress Dashboard, I would see a minimum of 250 pending posts. Almost everything would be a spam post. Thats when need arised for me to tighten my Techtate Guest post user registrations and to make a bulk delete of thousands of pending SPAM posts. While I surfed through the available WordPress plug-ins I found this BULK DELETE plug-in, which came out to help me clear all these annoying SPAM posts.

The first time while you attempt to use it itself, it would prompt you to use it with much of caution. Because, the bulk delete you make cannot be recovered once again. So my personal advice is also to use it with much of caution. You can delete posts my Type, Category and also even the Tags the post use. 
DELETE Criteria :
- Category
- Tags
- URL
- Pages
- Revision
- Pending
- Private
- Drafts
BULK DELETE Features:
- Fix Date Ranges within which the posts are to be deleted.
- Restrict to First X posts.
- Select privacy level of posts to be deleted.
- Choose if you should delete them or trash them.
Expected BULK DELETE Features :
- Schedule deletion of posts.
- Delete images that are being used by deleted posts.
- Bulk Delete Comments.
At some stages this Plugin might help you a lot. Happy Blogging
