"Supporters and/or players who have been members of a standard clan for at least 1 week used to receive 1 vote per week. Since May of 2012 the frequency of the vote has been changed to 1 day instead of 1 per week, a theoretical seven-fold increase. [from the help]"
We have 7 different voters in the Black Market right now, and votes count for 2 weeks. That's 7 x 7 x 2 = 98 votes if noone would forget a single vote. So 48 is quite realistic if we try to vote every 24h.
