Comment to Entry Ratio is not important

I don't understand why some of these groups require a high comment to entry ratio. I mean its just mindless thank yous anyways. Who makes a giveaway on this site and then constantly looks at it to "enjoy" all the mindless thank yous people posted? I could care less if I got a single comment on any of the giveaways I create. All I would like is the personal "Thank You" from the person who wins.

I truly thanked the people I have won gifts from. Even chatted them up a bit as well. That's what matters, not mindless comments on your giveaway.

Their Group, Their rules. I understand and that is totally their right. I just don't agree at all with that one rule when implemented.
