To repeat what I'd already said at ANI, I am not alleging a topic ban breach, except perhaps under the "broadly construed" wording. I am stating that, based on the manner of this series of reverts on The Automobile Association , followed by this 'rewrite', and based on the fact that HighKing has yet to make any associated comment at Talk:The Automobile Association, instead choosing to treat this as an issue of "vandalism", HighKing has inarguably ignored the warnings Cailil gave him when he re-enacted the BI topic ban about his future conduct. Those can still be seen on his own talk page under the "Removals of the term British Isles (again)" section on HighKing's talk page, so he has no excuse for not remembering them. You're going to have to read that whole thread to get the picture, but it shows quite clearly that Cailil was quite explicit in what he expected from HighKing going forward, in addition to simply adhering to the topic ban: he must stop edit warring and start discussing, he must stop this behaviour of policing terminology on Wikipedia, he must stop introducing (and maintaining by reverts) innacuracies (his altered version of the quote is not in the source, so is clearly innacurate). Basically, he was telling him to just go and find something completely different to do than this, because it is of no benefit to the project. What he has done instead, is just transfer his focus from policing usage of the term 'British Isles' on Wikipeda, to policing the term 'Republic of Ireland', while mainaining the same bad behaviours - edit warring, lack of discussion, misrepresentation of sources, misuse of guidelines/policy, etc, etc. As an administrator, the onus is on you to step in and stop it. Five years is long enough to be still getting away with this sort of WP:TE in the way you have so far allowed him to in this case. You need to block HighKing now until he gives cast iron assurances he understands why Cailil wrote those things on his talk page, and tells you precisely how he proposes to avoid it in future. That's it. As far as evidence goes, short of me pulling out direct quotes of what Cailil said to HighKing, I don't see what more you need to see, to do what is required of you.
