It's a software program, designed by a player, to supposedly fix your ping for better results whilest gaming in BF2.
The last thing I read, by an actual Dice administrator, was that it had no effect, and was simply in the minds of the some of the gamers.
(It should be noted that many who try it, don't believe it works at all)
Unless there has been some new news, then I think this would make it someting called, therefore, a placebo.
Something that has no effect, but still for some people works, because people
believe it works.

Noun
pl -bos or -boes Med an inactive substance given to a patient usually to compare its effects with those of a real drug but sometimes for the psychological benefit gained by the patient through believing that he or she is receiving treatment [Latin: I shall please]
