Automated Profile Spam Deleter

Need a desktop program (Visual Basic ok) that can log into multiple profiles within a single web community, identify spam guestbook posts (any post not made by profile owner), and delete said posts automatically by using "Delete" link provided for each unique guestbook post. Needs the ability to store login information for 80-160 profiles. Program needs to check each profile on a regular basis, desire ability to set to check this every x minutes. Need status results on # of spam posts detected, and # of spam posts deleted. Program must ignore posts from profile author other approved authors stored in the login information. Spam post can be identified as coming from an author who's profile ID string does not match any in the login information database. Need ability to set delay time in # of seconds from when program checks a different profile to ensure chat community is not hammered with http requests from single computer in a short time frame. Application needs to work on both XP and Vista systems, and be somewhat user friendly. Please contact me for more information.
