Coins101 is definitely Spreadnodes.  I'm not sure on others, but am positive on that one.

You mean with the current optimized miner being used by a couple large farms the chances of a normal person being able to acquire any spreadcoin by mining is next to none.

If you are mining spreadcoin with a couple of GPU's you might as well switch them to something else.  You have a better chance of winning the lottery than mining spreadcoin.  All your doing is using electricity.  Mining spreadcoin is now controlled by a few large farms using optimized miners.  

I thought the no pool solo mining only concept was great at first.  Then I realized it was just a ploy to be able to hide what's actually going on.  Private optimized miner, private pools.
