I do understand that, but I have to respectfully disagree. If I throw an add up in gen chat with what I require, I get replies. I then write down names and consult armory. If it looks like an alt, I ask if it is. If they say no, I check their gear to see if they are making an effort to be raid ready. I then choose who I take on runs based on conversation with the prospect and checking his armory. I know this sounds slow and tedious, but to me, it's worth the extra effort. The way I see it, people want others to be in their guild just as badly as others want to be in a guild. I wouldn't want to miss out on a good prospect just because of a technicality.
