After reading this question:
I had a strong sense of deja vu. Gooling for some code in the question led me to these other questions:
- How to replace values by NA in file 2 correspond to specified values in file 1?
- How to calculate the averages of a variable in several binary files based on classes in another binary file?
The style, type of data, and titles of the questions a very similar, leading me to believe this is actually a single person. My questions are:
- Can it be verified these accounts belong to the same person, .e.g using ip-address?
- Can these accounts be merged, or is it fine to let them co-exist.
