So about 3-4 months ago, I tried to post my website on Facebook (jenova.rf.gd). They marked it as spam and I sent a request to tell them it was a mistake. I had kept trying to post it around every month or so to see if they took the block off. Just yesterday they sent me a notification saying that the block was taken down. Now I'm not sure if that's for ALL the sites in the InfinityFree webhost or even if it's just rf.gd or even just my website. All this shows is that Facebook is able and willing to unblock your website if you are persistent enough.
