Error code 50 - User not found


I try to tweet this message:
M. D. Anderson Cancer Center Department of Genetics
and get error:
{“errors”:[{“code”:50,“message”:“User not found.”}]}
o_O what???
Looks fail.


The reason that this is happening is that you are starting your Tweet with an M which is SMS syntax for DMing - so the platform thinks you are trying to DM a user called “D.” and that doesn’t exist.
