So I did not have the opportunity to go to US Nationals this year. My league owner, however, did and told me that during the LCQ (which he did not play in) people were being offered rewards by players with a worlds invite to knock off certain players to limit the pool of people who could play at worlds.
...and thanks for proving why this should just be the TCG News & Discussion forum; gossip and the rumors they start can be pretty vicious and damaging. Your league owner should be reporting this (for what it is worth) to TPCi... and if it should be mentioned here, again it should be by that person with first hand knowledge.
I am not trying to be "mean" to you, but prevent you from making a big deal out of a potential non-issue. I don't know you, and frankly this sounds like an attempt at getting attention at the expense of others/community integrity.
1) Pokémon isn't conducive to headhunting; about the only way this affects things is if someone entered the tournament and planned on scooping past a certain point to avoid "grinching" others... and based on what TPCi representatives told us on the board, they
wanted players to play-to-win so that it wasn't too easy of an event (ergo this was probably not a good tournament to be scooping in anyway).
2) People make foolish jokes and similar statements all the time, and we need to be careful when we are at multi-day event and some (most?) people are running short on sleep that we don't take every comment seriously. "Give someone a box" isn't an expression, but it still might have been a joke comment, akin to "I'll give you a million dollars if...".
TL;DR: Too many unknowns here, plus if we take things at face value we have second-hand information that people are literally only guilty of breaking a rule... not for gain, but just because, like seeing if you can "steal" your own car (barring making an insurance claim against it or the like).
