Ummmm NO!!!! It's not odd at all. Perhaps you don't realize this because you don't see the advertisements, but:
A) That is actually a promo for footwear.com. They are using Skins to promote themselves. Nowhere does it mention a ticker symbol or a tag line like "buy our stock".
B) There are also advertisements for Scotttrade, Progressive, VeriSign, Viagra and other brand names. Should I be skeptical of buying car insurance from Progressive because they advertise on a stock message board?
