Publishers can get anything and everything in terms of complaints, real and imaginary:
Treat all complaints, particularly regarding copyright issues, very carefully.
Matters like defamation, libel, or breach of copyright can be extremely serious, and have to be checked out prior to any response. At the approach stage, it's best to take complaints on face value, and make sure of your situation before responding. A dispute can turn into a war with an ill considered response.
Do not put in writing any form of commitment until you've received appropriate expert advice.
Do not threaten legal action against correspondents, unless you are actually intending to take it. That response can be interpreted as bullying or coercive. It's bad, as well as potentially expensive, public relations, likely to be publicized by complainants.
