I have a joomla 2.5 portal, recently i was attacked probably by a SQL injection or something, the fact is that all my DB was filled up with messy articles and a lot of users, i already cleaned up my items/articles using the k2 item administrator manually.
I found near to 30k users on my DB, delete them manually is a pain, i want to create my own SQL delete script to remove them all at once, but i am not sure what tables are involved in the user control and i don't want to corrupt my DB.
Any suggestions?
Thanks a lot!
