Question in the title. Set wheelies down hard occasionally. How many times can I get away with it before I can expect leaks? Does suspension quality matter?
There's no hard or fast rule. The best bet is to inspect the bike before each ride. Generally, leaking fork seals aren't the end of the world; ride until one goes and then fix both. If you don't ignore the problem, you're unlikely to get into major trouble.
I'd recommend disassembly and inspection when you do the seals. Stunting will also be hard on the bushings; those should probably be replaced as well.
I'd also recommend occasionally throwing the bike on a stem stand. Check the triple clamps for free-play, and rotate the bars back and forth to check if you've notched any of your bearing surfaces. Hard landings tend to do bad things to your stem bearings.
