Well far be it for me to disagree with it then...

I am not sure if I am reading into things, but I do hope longevity was not being used as some sort of precident for something annoying or confusing. :)

But if you mean that it's been here a while and thus, I should know of it... well I don't. Even if it has been used, I think its use would be rather sparse. It is certainly not used as frequently as 'LG' or anything.

I even have proof! Check Wikisposure's article on Pedospeak#A it is not even listed as an abbreviation! They've got a pretty extensive list (they've even added shotacon, lol) so the absense on their page certainly is evidence enough to me for its lack of popular use.

I mean, that thing has terms I've never even heard of before. Wtf is a 'high boylover priesthood'? SYF is also pretty rare too, I've never heard of that before but PJ has, so if PJ hasn't even documented AG yet, it's got to be a rather uncommon word. Probably because not that many dudes around here like adolescent girls like you and I do.

I wish those guys would let me register as an editor so I could add stuff like that. Also it has a bunch of mistakes like lolicon/shotacon shouldn't be in caps. I think the person who added them maybe didn't know they were not abbreviations, or else maybe they were lowercase but some douche changed them to uppercase.
