I didn't know something like this was happening, but it's so cool, if you was basing this on the past 3 months I know I'd be there at the top lol, been a little quiet recently, need to get active again you just motivated me .
P.S when I post I'm getting automatic votes from you but sometimes they don't happen , a little info on how that works will be great.
Yes these are monthly based, featuring top users of eSteem and giving some reward and encouraging others as well. :)
As for votes, there are some filters but you don't have to worry about those, just enjoy your experience and time to time you will get a bit bonus :)
