The "incident" has to be pretty severe for you to be debanked in multiple EU+UK countries. Little less than terrorism would do it (I was going to say coup attempt might, but the Catalan leaders who tried to illegally secede from Spain didn't get debanked, so probably not).

Remember that Germany considers not liking the Gaza holocaust to be terrorism, and has issued Schengen area bans against EU politicians for this crime.
