Slimming World won't sue anyone for calling Syns "a load of rubbish" because they can't justify it in a court of law. One or two people have been insulting SWfor years,,..they've never gone after them because they know they can't.
From a company that is very litigious this speaks volumes

.
They go after people who use their name in other ways such as selling "SW recipe sausages" in butchers . This is because they do their own range though.
So RH can continue rubbishing them and SW won't do a thing. In fact my hatred of SW is right up there with TeamTH. ...can you tell
