A user on the Facebook group 'UK Places Editors' has commented on the 
fact that some maps on Facebook pages in the vicinity of Putney Bridge 
(London) show the River Thames as 'Thanames'. See, for example, 

A bit of browser debugging shows that it's accessing the URL 

Note the parameter &osm_provider=2

Can anyone shed light on what tile service is being used here and what 
could be causing the Thanames name to appear? I can see that adjacent 
tiles rendered at different times, so that the label 'Thames' occurs in 
a different position, could cause something that looks like 'Thanames' 
when they are joined together, but I can't produce any evidence of this.
