For context, the post applies to the current situation on EU-Golemagg. Your mileage and experience may vary.
The recently diminished server population and the relative ease of both Trial of the Crusader and Icecrown Citadel at high buff levels has spawned (or rather, led to the resurgence of) “GBID” raids, in which- instead of all bids contributing to a communal pot as in a regular GDKP- all bids go wholly to the raidleader/organizer.
These raids most commonly take the form of “SR” pugs with crucial items like tier tokens restricted behind bidding (with a minimum bid imposed), and all optional items like BoEs, saronites/orbs, bloods, and shards either hard-reserved or again left to bid. Curiously (or, perhaps, obviously), the same people advertising host multiple such runs on a weekly basis.
Now, an experienced player can easily choose to avoid this kind of trade chat nonsense. If you’ve gone past the stage of acquiring gear and logs, you can find high quality SR pugs or GDKPs to your heart’s content, depending on your preferences.
The reason why I’m bringing this up is because these raids are essentially set up to rinse new and freshly dinked players who haven’t yet built up either of these things, and are hence unlikely to be admitted to a reasonable, higher-quality PUG that doesn’t resort to this type of nonsense.
I’m not here to argue about the merits or demerits of GDKPs at length, but at least there is theoretically some benefit for all involved by attending one. These GBID raids, however, are genuinely predatory in nature and they make the already unpleasant new player experience of transitioning from leveling into raiding even more irritating than it already is. One can pick between the currently dreadful RDF queue times or dropping a thousand on a Trophy of the Crusade. Splendid.
In the event that the relatively higher difficulty of Cataclysm raids doesn’t naturally put a stop to this, and regardless of whether a general ban on all GDKPs takes effect for the expansion, I would like to suggest that this specific type of behavior becomes bannable.
Community blacklists, if they are even operated by servers, can only go so far.
