[FSPA] previously unknown pinball technique discovered?

[Joe Schober]

Really, the first thing that came to my mind was: OW.  Pounding wood/metal/glass with your fist for 15 seconds after every tilt warning seems like an orthopedic appointment in the making.  But props for finding something that does appear to work well.

While there isn't currently a published rule against this (at least in FSPA rules or, as far as I can tell, the PAPA/IFPA unified ruleset), I'll point out that there is a catch-all rule about "conduct exceptionally detrimental to the league".  While I do not personally think this inherently falls under that umbrella, it'd be a different story if a machine owner or location owner requests that players not use this technique on their machines or at their location.
