[OSM-talk] Way to delete buildings added by specific user, or help reverting?

[hbogner]

Hi all

Is there a way to delete buildings created by specific user?

Some users already complained about 
https://www.openstreetmap.org/user/Venko to me for inaccurate mapping 
and imaginary mapping. They wrote to him, but he didn't reply or stop.

Here is an example on which I just stumbled:
https://www.openstreetmap.org/#map=17/45.52874/15.48285&layers=N

He copy/pasted one building all over the place.

I tried to revert the changeset, but there are too many conflicts.

Any suggestions how to fix this mess?

regards, Hrvoje
