Vapor is NOT associated with Astralis in any way. He's wearing our banner because SoW took him under as an interest. SoW is not Astralis - I don't manage the way they run their clan. We share a TS and company, and we play together often. We're under the same banner for banner stacking purposes.
If you have a problem with one of their members, take it up with them. This is not my concern.
