After a while people tend to glue together into cliques with their friends, and often feel little need to branch out. If all the RP you want comes from the same 5 people or so, then why go get more? It's not a deliberate effort to exclude newcomers, it's just in people's nature to be this way.
Try asking people you've already RP'd with if they'd like to RP with you again directly, often people are pleased by direct requests for RP, as they are not all that common after a community settles. It can be tough to break in.
