>>9735686BZPower was an early version of influencers. They were directly backed by Lego. Among other things they received prototype pieces, literal crates of sets for their personal libraries (so they could build stuff and showcase what you can do with the product as an unaffiliated group), and sets they were supposed to use as prizes for competitions. What happened was that they would use the competitions to give the prize sets to their cronies and mods. Even when they didn't, the most likely people to win a competition are the ones with whole crates of free parts.
In the case of G2, there was a contest where the prize was a literal golden mask. They had a shoestring budget and yet they blew it on this frivolity. Anyway, the prize went to a known BZP crony called RoaMcToa. Her win was controversial because she used parts that weren't even available at the time. The judges defended their verdict by saying that the parts in question were available to anyone attending a certain event that was VIP only, and the BZP cronies were invited (with expenses paid). An article in a magazine also tried to promote Roa McToa with the title "Who said girls can't moc".
The contest's result was a disillusion for much of the dwindled fanbase. Even if the judges are fair, the average fan has no hope against builders with a room full of parts. Parts they were given for free from the company itself.
