Ok I got a bone to pick with pinpins

My address is 123tsfqm8UmK3UYs3ysLWtEfmXt1fhTcF4, I have been mining for a week in solo or party and hardly find any blocks at all. Now I went to a friend today that has some antminer l3's his address is 17UtYuUAh83Do5i2CGmG8MFBXqACqcz2Gr we setup a party together and have been running for almost 16 hours now and his miners are finding blocks but mine dead in the water.

Please see if my address is on a blacklist or something.

I mean seriously I used to make 0.0025 a week.

Am I'm just having the worst luck ever or is there something up.
