ypool.net is not a scam.
I fully support the pool and the dev's behind it and the third party devs that work with ypool. The devs are some of the most talented individuals in the scene today and have a solid reputation built up in this community. Anyone saying otherwise is ignorant of these facts and they most likely have no reputation built up in this community.
+1 on this, they are the only ones actually running a pool that is worth anything, and its running right now in spite of DDos attacks. Not to mention only pool that AMD GPU mining works on.
If you want to get angry get angry at the maxcoin devs
