I was just wondering the same thing because I had listed them on the following list over a month ago
ISP's known to BLOCK or Filter p2p or specifically Limewire but I don't know if it still applies. I had been thinking of sending a pm to a few of those people concerned. I guess you could search optimum on the forum & send a pm to those members who were also having problems.
I would keep nagging optimum if I were you. Ask "when" you'll get your full service back again.
