Hey, who are we to judge. He/she got many uncles everywhere, also probably one named Sam in the states. 
Same vibes coming from this mapper. Suspiciously mapped the name of many, I dare say probably 1000 or more unnamed highways around the city of Kulim, Kedah - numbers assumed from ~550 changesets.
When asked about the source, the mapper simply just said they were from " taxi driver, and know streets well". Wow, someone who knew 1000+ street names by heart (right).
The dead giveaways were as clear as the day: abbreviations of street names were inputted instead of typing the full street name. It’s another red flag for me, because it seemed like this mapper had likely lifted these names from a map database, rather than a real person, if it’s even true (no one in Malaysia abbreviates Jalan - Street – as simply “Jl”).
Up until today, the said map database is a mystery, personally. This is because, even popular map providers with coverage in Malaysia, do not even use these kind of eccentric abbreviations (only maps of Indonesia do that IIRC).
Uncle Roger, got many nieces and nephews.
Another changeset from one of these mappers (the one with the “uncle” above): https://www.openstreetmap.org/changeset/94135189 . This one looks just based on aerial imagery.
Wasn’t this guy reported before and already suspended?
In a probably relevant question, is there a competition or something among the russian mappers that get points from their edits in OSM? I found another guy with a russian name doing street names around here but I haven’t bothered to report it yet.
and the guy has a good name: “манагер1234545” (i.e. "Manager1234545).
On the other hand, he is no more active since more than a year already.
And there seems to be only one more Russian “pere-ulok” in Malaysia:

plus a malay-russian double name at node

See also an Overpass Query:

that overpass query result is rather unsettling. The road names without the “Jalan” in front and wrong name structure suggest that these are imported from somewhere else. Shit never ends…
and a shopping center on Langkawi:

That’s all which I could find with an updated overpass query for Russian characters in the name tag .
That’s neat!
Remember this? Many thanks to the Data Working Group, one down, all edits coming from said user is wiped.
