> between two internet mobs headed by two unsavoury individuals
This is a bit too much "both sides are bad" for me. Fact is that Kiwi Farms is a horrible website where people harass others, share information about them, and drive them to suicide. That's pretty bad on its own.
Look at it from Cloudflare employees' point of view though. Do they really want to spend their time getting drawn in to any more of this trivial online drama? No, of course not. Pulling the plug is the sensible business decision.
