Conversely I think that's why people dislike them, whereas they were much more popular 5+ years ago with fans from other teams.
Interestingly, there was a report around 2018/2019 where it essentially showed their social media sucked and they had the lowest level of engagement because they mostly posted in German, compared to other CL clubs. Since then, their tactic has been to be a 'banter' account and target large opposition fanbases to drive engagement. From a numbers perspective, it works. For example, they are shameful in their Sancho related posts (you all owe him an apology etc. then going completely silent when the loan ended and showing zero interest in renewing or buying at a knock down fee) because it triggers a large % of the United fanbase, same with PSG - they waited like 5 years to troll them after that Haaland celebration thing, did the thing with Barca being crap at corners, Newcastle they posted clips of Geordie Shore etc. It is an M.O. that works only going of social media interactions.
I think the issue is they are the social media equivalent of Maupay, when you're not good enough to dish it out as much as you do, it just gets stale.
