Database Error - Can anyone help?

I am getting the following Database Error:

Database error in Castration Fantasy

Query:

INSERT INTO `sys_tags` (ObjID, Type, Tag, Date) VALUES ('40', 'profile', 'sweet', CURRENT_TIMESTAMP)

Mysql error: Duplicate entry 'sweet-40-profile' for key 'PRIMARY'

Found error in the file '/home/ryanslin/public_html/castrationfantasy.com/main/inc/classes/BxDolTags.php' at line 255.
Called 'db_res' function with erroneous argument #0.

Any help would be appreciated, thank you!

When posting database errors. Only post what is above the line Debug backtrace:  Do not post anything below it unless asked for it.

 Sorry, I didn't know...  It's fixed.

How often does it happen? I usually only see it when spammers join the site. The tag already exist is the cause, and it's a bug in dolphin. Can be ignored. It will not cause any harm. Hopefully they will have it fixed in the next version.

I do keep getting spammers signing up.  Getting really tired of banning and deleting.  OK, I will just ignore it then.  Thanks...
