Is this a bot? I don't get these comments that say this.. I'm not sure what that means?

It's a bot that tries to boost minnows (low SP members) posts. It's one of many that tries to help new people here. I have seen another one called @randowhale, if I'm not mistaken, but there are others as well.

I see I see. Thanks!

It doesn't really matter, you see what's happening tho!? You jump on this bandwagon and vote or do whatever you can, promote interact, reply etc..
