Help, Listal now blocked at work. Says unsafe?

Help, Listal now blocked at work. I used to access Listal from work several times a day but last night that ended. Listal is now blocked by my companies safe site protection software. Did something change with Listal?

I can't see any reason why it would be unsafe. Does this effect just listal.com or betalistal.com as well?

Do they block many other sites? I'm guessing they block other social networking sites like myspace or sites that people spend a lot of time on like youtube.

They've always blocked myspace and youtube but never listal till just last week. I just thought it was odd that all of a sudden listal was now blocked.
