Jane Miller made headlines when she was seen repeatedly hitting a masked saboteur with her riding crop in a clip which sparked a police probe last November.
However, the 57-year-old was killed on Wednesday after falling from her horse while taking part in an organised drag hunt in Surrey.
And an administrator of a group named 'Stop The Cull' shared news of her death captioned: "She won't be missed by us."
Some even used the laughing emoji underneath genuine of condolence messages.
A Facebook post from the Mid Surrey Farmers' Draghounds group revealed Ms Miller's death on Thursday.
It read: "We very much regret to inform you that Jane Goring was tragically killed whilst out dragging yesterday at Leigh.
"On behalf of the masters and members of the drag hunt, we send our condolences and thoughts to Richard and Jane's family at this awful time."
Relative Alice Goring also paid tribute, writing: "The cruelest reminder to live every day, because you never quite know when your time may be up. Sleep tight Jane, we will never ever forget you."
After footage of the original saboteur incident – filmed in Hailsham, East Sussex last November – went viral police decided there was not enough evidence to proceed and dropped the case.
Just last month, the pair travelled to Brighton Magistrates' Court last month where she pleaded not guilty to beating South Coast Hunt Saboteurs member Simon Medhurst, reports the Mail Online.
She also denied assaulting another saboteur by "riding her down" with her horse.
At the time of the high-profile incident, her husband insisted she was the victim and was “terrorised” by the "hooligan".
He told the Daily Mail she was "very scared at being surround by a load of terrorists".
"This guy knows nothing about horses, he knows nothing about how to treat them.
"All he knows about is how to be a hooligan. Anybody would have done the same thing."
