[uMap] Delete or edit a frozen public map created without an account

[basil]

Hi to all uMappers,

the scenario is the following: I use uMap without an account to create a 
map, and accidentally set the map to be public, because this is the (not 
so obvious) default setting. After a couple of weeks I find out that I 
cannot edit, let alone delete the map -- if there was a warning or 
disclaimer about this I must have missed it. Then I create an account, 
hoping to be able to delete it, or at least edit away information that I 
realize is sensitive, but I'm still not given this option, since the map 
is not attached to the account. The map is now public, searchable, and I 
seemingly cannot do anything about it.

How should I proceed, given that there is no direct uMap Support service 
available, that would handle the situation discreetly?

Thanks in advance for your feedback,

Basil
