Good recommendation on the $500 bonus whoring idea. Is this because most maximums are in fact $500?

I'd like to bonus whore AMAP, to maximize my account. Is there a link to a 'line' of whoring? I think this would be a great idea, unless there is no line if your BR is above all maximums.

But a list of all of the sites maybe? I know FTR has some info on it, but is it updated regularily?
