Welcome to OpenStreetMap.

I'm not sure what you were hoping to achieve here, but I'll try to help if I can.

There's no need to add additional parks within a park which has already been mapped, as Plumstead Common is already mapped as a multipolygon relation:
way/262748978

A park shouldn't normally be mapped as a node, but as an area. The documentation on the wiki is here:
leisure=park

Many thanks for the reassurance and good luck with your project.

Removing the layer=-1 tags set by Waymap's @alisonlung would help. They appear to have been added because she didn't know or care what she was doing. It took a long time to undo her more damaging and pointless edits.

Please could you confirm whether or not this is part of an organised editing activity by or on behalf of Waymap?

Where a sidewalk goes around the corner into another street, you need to split it before setting the name tag(s), otherwise turn-by-turn instructions will be unhelpful (e.g. junction of Devonport Road Scotts Road).

It would also be helpful if you added or updated sidewalk tagging on the road itself.
sidewalk=*

* Buckingham Road, not Bicester Road

I wonder if this could be a bug in iD? Presumably the edited node was intended to be somewhere in Kota Kinabalu rather than British Columbia?

Was the deleted public footpath LB Croydon FP 127 incorrectly mapped, or has it been formally stopped up or informally obstructed?

@AndersAndersson The only beneficiary of this vandalism is the Russian side. If the operator of these sock puppet accounts is actually Ukrainian, they're collaborating.

@basilEed1524 by damaging an open source project you're more likely to erode support for the Ukrainian side. I'll assume that you are either a Russian, or a collaborator.

As you're reverting them, nobody is going to worry about the odd typo or speling mitsake :-)

You should be safe. Vandalism isn't civil.

Your edits and your account being then most unwanted data in OSM at the moment. Go away and grow up.

There are no tourist apartments on the Great Eastern Main Line. These changesets have been reverted, as were the similar ones added by @Saj93.

However, as you are using the abysmal MAPS.ME app, it is possible that you were trying to do something else and this was unintentional. If you are trying to map something unsupported by your app, please leave a note via the website instead. If you are trying to leave a personal bookmark/drop a pin, please check your settings as these were added to the public OpenStreetMap database.

This looks like a personal bookmark created in error with the abysmal MAPS.ME.

Removed in changeset/140118399

@BCNorwich No, it was just vandalism. See also osm.org/user_blocks/7410
