Hello again,

It has been several days since I first contacted you about the sources for your edits since I found them to be highly unlicky to be correct

Since then I have done an internet search for changes of speed limit on I290 and MA 2. Both searches came up empty. I also checked the speed limit on I290 while I was commuting on it. The limit is still 65mph. 

At this point I can state with certenty that this changeset and your others on I290 are fictional. Keeping this in mind it is highly likely that your speed limit changes on MA 2 are also fictional.

Editing of this type is defined in the OSM wiki as vandalism https://wiki.openstreetmap.org/wiki/Vandalism#Vandalism_and_other_types_of_bad_editing

This page also give me the privlage to revert edits that I can prove degrade the quality of the map data on OSM. 

Therefore I am asking that you please revert the speedlimit changes back to the previous values.

If I do not get a response from you by 6PM on Sunday the 7th (tomorrow) I will revert your edits myself.

If you have any questions please do not hesitate to ask.
