Does that sound silly and unrealistic? Sure it does. But it has the potential to happen. And it has happened in the past. People have learned their lessons, and that's why trademarks exist in the first place. Better to snip at it now and risk the wrath of a couple faceless internet posters for a thread or 2, then to not do anything about it and be subject to scenarios like this 10 years down the road.
Care to provide some examples of these sex toys and child labour products that were sold because someone didn't trademark their nick name?
