Legitimacy when it comes to leeching?

This is the way i see it, the people who want to be leeched pay mesos, which they probably have gained from a different character. Most likely if they are paying for the leech they've already completed the lvl 12x milestone once, why do it all over again? If you proved you could do it once, why should you have to prove to do it again? Besides i know at least 95 percent of people here in their hearts if a bishop/archmage came up to them and ask if they wanted to leech a character they'd say yes.

I can't help but wonder if NEXON will catch up to this way of leeching and start putting experience points in bundles into cash shop for you to buy LOL. Just like they did with mesos.
