He missed chapter and verse about this on Harringay Online (or perhaps he didn't - we've been on page 1 of Google search results for "Harringay Tube Station" for years) - https://harringayonline.com/forum/topics/tube-station-in-harringay
Wow - amazing
I commented on his video with the same link and another link to HoL to help users with their Harringay / Haringey confusion. Both seem to have been deleted. I wonder why?
I've just stuck a link to your piece on the video comments, be interesting to see if it stays ;o)
Sorting the comments by 'Newest first' just now [2 hours later], can't see it...
A bit pointed, given the information quality of some of the other 250 comments.
A couple do have URL links, so it may well not be a blanket autoblocker.
Youtube algos remove external links in comments as a matter of course. Youtube and some other Google family links are usually fine (the only links remaining in the comments on this video).
