Just think about it a bit different:
if someone can solve his/her problem with $10, it's OK, not a big deal
but an account farmer, who farms 100s or even more accounts, it costs 100 times more, at least $1,000 to buy copper membership for the farmed accounts, to be able to continue to spam and earn with that army of spambots... (but I'm sure who has 100 farmed accounts, it's not a big deal for him to pay even a few 1000 dollars for copper membership...)
I realy cant imagine someone doing anything with 100 acc!! Only to log in and write one word with all of them is huge work
