LashBack Universal - Don't waste time following links or filling out forms just to get out of spam lists. LashBack is an all-new, patented software package that installs to nearly all Windows-based PCs and is so simple that anyone can install and use it. Simply forward offending messages to our servers, and the program will search the spam for an opt-out mechanism and automatically unsubscribe you from it. But that's not all: If enough other LashBack users report a specific spam message to the LashBack servers, you'll be opted out of it before you even get it.
