Andrew Torba (of Gab) noted that his Breitbart post on the Nelson forgery was flagged by Facebook as being "disputed by PolitiFact:"
Gab tweeted: "This is unreal. Facebook is attempting to police the sources of information you share..."

Jim Hoft of Gateway Pundit pointed out that Facebook took down their articles on the Allred/Nelson forgery as well & pointed out that Facebook censorship amounts to picking winners and losers in the Alabama Senate race:
"So @Facebook also took down our #Allred phony signature story too— #Facebook is picking winnere-losers(sic) in #ALSEN race"
