If fans started banding together to regulate deathmatch spots, it would almost 100% lead to a streissand effect where more people would flock to deathmatch wrestling. Same way Gail, cornette, anyone who has a big enough platform to spread things to others are essentially doing exactly what they are so against which is growing a style of wrestling they hate by providing so much attention to it.
Gail / Corny will not change the mind of a deathmatch fan, nor would they convince their own internal audience to check this out as they will adhere to their opinion or already dislike such a thing. It's the people in the middle who may just happen to see Gail's tweet (follower or not) who are being introduced to this that will turn either off or on, but even one person being turned on to this is a net positive for deathmatch wrestling lmao.
In turn I just explained what a grift is, which is performative outrage with a result of contributing to the problem you so very much hate.
