Personally? Nope but I know what seo abuse looks like, I know what the anatomy of the biceps is, I know what the results are from seo abuse, I know muscles don't change shape over night on their own.
That "you know them?" Crap is weak. Everyone comments on people, you included, do you KNOW everyone you have ever commented on or so you have the ability to make simple observations? Hell their seo use is known.... It's not a big secret in the sport. Almost all pros use it and that's fine.... But abuse is obvious.
Gee I hope you have never commented on HGH gut or anything like that .... I am sure you don't "know" them.
