No? There are a lot of studies showing positive benefits:
>The primary benefit of creatine is an improvement in strength and power output during resistance exercise. Creatine is well-researched for this purpose, and its effects are quite notable for a supplement, both in the general population,[6][7][8][9] and specifically in older adults.[10][11][12] When used in conjunction with resistance exercise, creatine may modestly increase lean mass.[7][12][11][13] In trained athletes, creatine has been reported to reduce body fat and improve some measures of anaerobic exercise performance, strength, and power output.

And as a general rule of thumb: Don't take anything from 4chan seriously.
