Nonsence nodes in the dataset

[iBobik]

There are nodes like this. What it means? Should I ignore it?

Maybe deleted places?

Yea, those are deleted places, everything with deleted_at != '' should not be displayed. Our client apps rely on caching and they need to get notified of places which stopped accepting bitcoins, that's why we also return the deleted places. Our endpoints are append-only, nothing really gets deleted.

It's not strictly necessary for the initial sync, when the caches aren't yet populated, so we may add a filter flag in the future, but there is a risk that this flag will be copied to the follow-up sync code, messing up the caches, so there are no perfect ways to avoid those footguns.
