If I recall correctly... they've been following Binance for a few months now. I think it was like the 1st or 2nd account they started following. Only reason I even remember that is because they had to put out all these posts telling people to stop spamming Binance with messages about listing Safemoon, lol.
I wonder if that answers the question about Binance... since the only two coins that are currently linked with SFM on the Safemoon site are Etherium (whom we are bridged with) and Binance...
There will be more linked soon. I just think it's another bread crumb on the trail to the Binance bridge.
