It is a very bad idea to delay relaying/accepting blocks based on information which is only local to your node (ie would create the ability for people to split the network by sending out lots of double-spends to different parts of the network at the same time). Thus, miners are incentivized to go connect to everyone on the network and look for double-spends, not including them in their blocks to avoid being delayed (which is OK, except having to connect to everyone is bad). There is a related concept of "discouraging" blocks which generally only refers to mining on a previous block, but you have to be careful doing that so you dont break consensus.
