What should we do with invented data in OSM and Wikipedia!


I have a small problem. Some User from a small village fakes the data in Wikipedia and also here in OSM. The Problem is that he invented the National Highways NH233A and NH233B.

Around every 3 month he tries to implement the wrong data in OSM. Normally I repair afterwards every relation, road classification and wrong naming. Afterwards he created 5 to 10 accounts and tried again to implement the wrong data. But this is from me no problem.

I wrote all Users that they shouldn’t implement wrong data but I got never a reply.

Now my question:

How we get permanently the wrong data out of Wikipedia and is there maybe somebody with Hindi skills to write a message?
