Compiled by @KeepBackups, I just neatened a few #FF lists in-to categories etcetra. I don’t know some of these people, but I do trust & know the people, who #FF’d them in the first place. Contact me on Twitter if you have someone, 
who should be added and or if you want to be removed.
Still adding more people, looking for more lists too, DM me if you have any.
Thanks a tonne to, Toffee for giving me some more Malware people to add.
