Looking at the site Max it's not 6 pics, it's the site as a whole.
Factors as a whole that can contribute to Visas decision:
1) The trojan found on your tour page
http://barelylegalguys.com/tour01.htm
2) The terms "barely legal" "twink" "boys" "innocent" "school boys" "virginity" "deep penetration" "extreme fucking" "virgin twink boys" "just old enough to take it up the ass"
3) Undoubtedly they followed the link to your
http://www.twinkguy.com site where you use the keywords "slim" "school boy" "twinkie" "boy" "twink" "young"
I'm not saying I agree with them, but I understand why you're having problems now.
