[Talk-ca] Dubious edits by User:Yathusan

[Andrew MacKinnon]

I have noticed several dubious edits in the Toronto area by
User:Yathusan. They are all very inaccurate and have no GPS traces
supporting them, and I suspect that they are vandalism (but I am not
sure, they might just be very inaccurately done legitimate edits).

http://www.openstreetmap.org/browse/changeset/2228347 - adds a
footpath underneath Highway 400. Very inaccurate, no supporting GPS
traces, and in the middle of some industrial buildings. Have reverted
it for now.

http://www.openstreetmap.org/browse/changeset/2227889 - extends
Greenview Avenue several blocks south of Finch, in some places through
houses. Same as above.

http://www.openstreetmap.org/browse/changeset/2227844 - undoes the
mapping of the Doris Av extension done by Richard Weait, makes it look
like the satellite photo. Not 100% sure about this one, haven't
reverted it yet.

http://www.openstreetmap.org/browse/changeset/2227665 - northern
extension of York Regional Road 99 (extension of Highway 427) past
Zenway Boulevard to Langstaff Road. Very inaccurate, but plausible
since this extension is planned in the future (though Wikipedia says
it hasn't been built yet). Can anyone confirm whether this exists yet
or not?
