I've not seen signs of this: on the contrary we have had to work hard to get Twitter to ban the worst of the worst (e.g. socialist accounts who argue openly for military attacks on Ukrainian civilians far from the front lines - or even worse).

It would be great if the same Twitter that finds it OK to throw out Babylon Bee for having fun with a government official would also be consistent enough to throw out tankies that more or less (you should see some of the things I have seen) argue for genocide of Ukrainians.

Same goes for hate speech against Jews, it is amazing what some people can get away with on Twitter.
