I’m starting to see this. Over on Mastodon I’m starting to get devisive pro-Reform stuff in my feed. Often it’s someone boosting (though not sure why) a video from a pro-Farage account and making a silly comment about it. The local instance I’m in is nice and friendly - and I don’t want the arrival of people who just want to stir up things. We do politics there and seems left-leaning but it’s courteous. Occasionally a tone deaf elephant will thunder through and then move instances when they realise we don’t like the being nasty stuff.
