In addition, be careful of where your chapter posts stuff on the internet in general. You would be amazed at how many pictures by different GLO's my friends and I have found on Webshots that show them hazing the new members. In a few pictures, you could even see the composite that has the sorority name, chapter, and crest.
I'm not condoning hazin, but if you really feel the need to haze, don't post your pictures on the internet where everyone could see them and could get your chapter in trouble, as well as give all greeks a bad name.
