Disabling sprite slot 7 is easy using Lunar Magic's "Change Properties in Sprite Header" dialogue. Just use a Sprite Memory setting that doesn't allow sprites to spawn in slot 7 (setting 08, for example). And while this technically doesn't prevent someone from spawning a reznor, it prevents that the reznor finishes the level, which, in the end, is all you really care about anyway. So yes, there's an easy way to prevent Reznor breaks and the tip is legitimately useful.
Edit: To be a bit more constructive, here's how I'd reword the tip.
Using Lunar Magic's "Change Properties in Sprite Header" dialogue, you can adjust the sprite slots in which sprites can spawn. By using a sprite memory setting that doesn't use slot 07, you can easily prevent Reznor breaks in your hack.
The tip maybe affects too small of an audience to be presented on the main page, though. But if you want to have tips specifically for pit hackers, this is the level of complexity that's needed for a tip to be of any interest.
