BWB/Amazon imports creating author records containing role name

There are thousands of bad author records which have been created from Amazon and BetterWorldBooks (BWB) imports where the string is not an author name. This particular version of the bug references those names which include role names (e.g. editor, translator, illustrator,...) and abbreviations thereof (illus., trans., tr., ed., )

Any attempt to create author records containing these forbidden strings should be rejected. Although I've listed a few examples, a comprehensive list should be constructed.

### Proposal & Constraints
All author names containing any type of role should be banned, rejecting attempts to create author records containing them (except for legitimate uses like "Editors of Reader's Digest", although those should arguably be just converted to the name of the organization/publication).
