Recently the block is full of spamming transactions (
http://www.cointape.com/). This situation have been for a while . I thought it was a test, actually not. If you don't include more than minimum tx fees, you have to wait long to get your tx confirmed. At the moment we have no implementation of large blocks yet, so we have to pay extra tx fees to miners.
what if i told you it was mining pools doing the spamming.. filling up blocks to force people to pay them more...
