This is probably down to the fact that it's highly unlikely that it's high club level - in fact that rarely exists in British league tennis. You get such a wide range of weirdos in club tennis that you have to make the decision on a case by case basis if it bothers you.
All is fair. That being said, my wife, who is a 2.5 and I are starting to play mixed together. Since 6.0 isn't an option, we will play 6.5, which makes it likely we will face a 4.0 man (I'm a 3.5). Although it is certainly permissible, I might take exception to the 4.0 hitting full-swing forehands at her at the net. There are so many other ways to win (she probably has a far larger hole in her backhand volley than anywhere else), and playing like that shows a lack of grace and sportsmanship. I have yet to run into a higher-level male player who would stoop that low.
