Okay so as most of you will know alot of people buy / have alot of gold nowerdays. And you get some people who have more gold than sense. These people often want to join some guild's big raid to BWL / MC / AQ to buy epics. This scam is aimed at those type of people.
If you're on a server, with a successful guild with the letters "L" in, this scam will work. For example, if on your server there's a guild called "Filan" it will work.
How to do this scam:
1) Make a guild charter and name the guild <Filan> (the name of the successful guild on your server with an "L" in it.)
2) Find some noob who obviously buys gold (Possibly has BoE's in every slot).
3) Say to him somthing like "Hey, we're raising money for flasks for out MTs in naxx and we're wondering if you want to join Filan for a price of 1000g, and for this price, we'll take you to AQ / BWL to equip you and when your gear is suitable we'll take you to naxx and you can start gaining DKP."
4) Hopefuly the noob will jump at the oppertunity and buy the gold and ask for an invite.
How it works:
WoW's in game font displays "L"s as capital "i"s. So capital "i" looks the same as a lower case "l". Meaning you can look like your character is in that guild.
Anyway, I havn't looked long on these forums but I hope this scam / exploit works for you.
(And sorry about my bad English, it's not my first language).
Didn't really know what to tag it as, sorry. =)
