The description of the group, says "this is a group for CS GO silvers and why we are humans ." The word "why" is a subordinate conjunction and starts the adverb clause "why we are humans." For an adverb clause to exist, a verb, adjective, or another adverb is needed. Because of the lack of a verb, adjective, or another adverb, you may not use that adverb phrase by itself. The clause you have used is a noun clause, and with a noun clause, you may not use the subordinate conjunction "why" to start off the clause with.

Also, the word "this" in the beginning of the description is ambiguous and has no antecedent which it refers back to.

Finally, the spelling of CS:GO, or Counter-Strike: Global Offensive is wrong. The description says "CS GO" without the colon (:), the spelling of CS:GO is wrong.

I hope this comment helps.
