This edit was made by downloading everything in Waterloo Region edited by raptureboi [1], then going through each crossing and barrier=kerb to look for obviously incorrect tags. "Obviously incorrect" means things like bad geometry (e.g., a barrier=kerb on a node shared by multiple sidewalks), or curbs tagged with tactile paving when nothing resembling tactile paving is visible in 2024 imagery. If one of the tags was obviously incorrect on a node or way, I deleted that tag, as well as any other tag I couldn't verify via aerial imagery, such as whether there are (lowered) curbs.

This user has been adding these tags all over, even in cases where they are incorrect, as verified by aerial imagery, street-level imagery, and ground surveys. Tagging things as wheelchair accessible when they are in fact a raised curb that leads to a patch of grass is the sort of thing that makes the map worse than useless, so I reached out to raptureboi multiple times over the past few months, with polite comments on changesets and private messages, but they continued to edit without replying to me or addressing these issues. My most recent message let them know that it was my last warning before going to the DWG if they didn't at least reply, and while they didn't, they do seem to have stopped mapping entirely for now, so I'm trying to just go through and fix as much as I can myself.

This changeset is conservative in the sense that, despite the problematic mapping practices, I'm only touching tags, and I'm leaving anything that looks plausible. E.g., I've left lowered curbs when they didn't have any other obvious geometry or tagging flaws, and I limited the changeset to Waterloo Region since that's what I have 2024 imagery for. I also left in features whose tags are from raptureboi, but the history shows as originating from me because of my previous attempts to improve these features (e.g. by splitting curbs), since those are harder to find. I should have just done this at the start, but it took me a while to realize how extensive the problems are, so it's all a mess.
