While this is certainly a matter of operating preferences, my preference 
is not to bother with callers more than a few hundred Hz off frequency 
for at least three reasons. First, I've tried to protect my CQ frequency 
by keeping it active. If I work someone widely displaced, my frequency 
is unprotected while they're transmitting. Second, if they're that far 
off frequency, they're likely to be getting QRMed by a station on their 
frequency, which makes them hard to copy. Third, if they're that far off 
frequency, they're more likely to be lids, and thus more likely to take 
forever to finish a QSO.

For the same reasons, I won't respond to someone signing /QRP. Not 
because I don't want to take the time to work a weak station, but 
because that station signing /QRP is likely to be a lid. Indeed, by 
sending /QRP he/she is wasting time doing so by sending un-necessary 
information. I work a LOT of QRP, especially during DX contests, with 
more than 160 countries confirmed, but I've never signed /QRP.
