I help run the anti-spam team here at Weebly, and I can report that we're not observing any notifications from Facebook indicating that sites on the Weebly network are blocked. I've run a few tests using some popular sites on the network, and wasn't blocked from posting any of them.
More importantly, the site that the OP posted is not hosted on Weebly.
I recommend reaching out to Facebook for more information.
