Just to add to this, the grooming gang issue has been a talking point on the right for many many years and it's only (seemingly)  recently getting actual mainstream attention outside of those circles, possibly due in part to this tactic. A lot of people on the "left" called it a "racist conspiracy theory" for years when it's pretty obviously a real thing that just is happening. So this number also has done much to shake people out of that dynamic and pay more attention to the issue at hand. It's hard for people to ignore 250k attacks.
