Blipping throttle ?'s...what's the right way of riding 2 strokes?

There's a lot of possibles to a seizure, but there is one thing I will always do whether coming off of a long grass-track section, dirt road, or otherwise long sustained high RPM use (as a saftey precaution) prior to closing the throttle.  I always hit the kill switch while the throttle is still wide-open (or turn it wide open) to hit the piston with cooling fuel & lubricant.  Remember, 2str's carry their lubricant in the fuel.  A hot, still revving piston suddenly starved of lubricant and fuel can seize (the term 3 or 4 corner seizure depending how many sides stuck to the cylinder). This is why I always mount my kill switch dead next to the clutch side grip.  

Beyond that trick, other ways to minimize a lean/lack of lubricant seizures on a mechanically tight & well cared for bike are using as high a flash point pre-mix oil available (my favorite blended variety is Maxima Super M, it's flash-point is one of the highest for a synth/org blend & likes mix ratios of 32/1 or 40/1, ideal for KX's). Do not using ANY castor bean pre-mix oils UNLESS you plan to dump your gas out after the weekend (degrades within a day or two once mixed, loses it's ability to lubricate & doesn't stay mixed in cold temps).  Proper jetting & a spotless filter so no debris clogs a jet (knowing what pinging/crackling sounds like is important too).  Jetting for & using 110 leaded race gas (your crank seals will thank you for it, but in addition it's always consistent unlike pump gas & the higher octane offers a bit of fudge factor & a performance boost too if jetted for it).

If your jetted correct or even rich, the motor is in good shape, and you use a good quality premix then you have little to worry about.
