This approach is the same as for 'Nigerian inheritance' scams - the whole point of an aggressive start is to ensure scaring away people who aren't going to fall for it, so you don't waste time on them.

The parent poster is perfectly happy with scaring away girls that want their emotional needs taken care of, since he's looking for something different anyway.
