How can I avoid drop hacks and crash hacks on Battle.net?

From time to time I play StarCraft: Brood War on Battle.net since it's still a pretty good game even after all the years. The only problem I have are players that come and mass drop hack everyone, or even worse, mass crash hack (causing Starcraft to crash) everyone playing games.

I have found some programs that claim to help protect against drop hacks online but I don't know if I can trust them. I also didn't find programs to protect against crash hacks although I think they exist (because people in SC tell me they do).

Does anyone know of a way to deal with this problem?

A very simple solution that can help is to have /dnd on when playing, and ignore a person who is threatening to crash you or who you think might. This will prevent the text character issue, which was the most widely proliferated drophack a while back because it's essentially undetectable.

If that doesn't work, there are some legitimate programs are out there that will help prevent these crashes, but they're generally incorporated as a part of a larger hack. Using these fully will have features that are at risk of detection by Warden, Blizzard's anti-hack. Stick to mainstream sites and read forum discussions about programs before you risk trying them out.
