Thanks for your helpful comment, Saddleworthian. It's worth saying a couple more things.
I find wordsearches mind-numbingly boring, consequently I don't spend a lot of time on them. So, frequently, though I may have spotted one answer that perhaps fits the bill, I'm not confident that it's either the only answer, or the 'right' answer.
In this instance, the setter gave no indication as to whether the 6-letter word was in contiguous cells, in a straight line, in the shape of a letter, or scattered all over the grid.
Considering all the deceptive messages sent out, it's equally plausible that the hidden word might be 'Athens', 'Narvik', 'Ostend', rocket, 'Rostov', 'Sicily', 'Tromso'...
The complainants don't number among the more frequent contributors on this site. I suspect that they are usually found on another site and have crossed over in order to stir up trouble.
