any one else noticed more 4 o kind on Ultimatebet freerolls?

So I play alot of freerolls (kinda a junkie) but I have noticed since Ultimatebet added the bad beat Jackpot I hve been hitting alot of very big hands.
The other day i had 4 four of a kinds and one str8 flush. and seen alot of other people hitting too. I love Ultimatebet but do you think they can tweak there software to make them just a little more probable for those of us playing the freerolls to entice us to deposit to hit the big win at theses new tables.
