I think you misread my post. We DON'T check. It's a non-discriminatory, all-encompassing policy. We're simply not going to party with randoms during that period. Our guild has enough active 60s in all time zones to do nothing but guild 5mans for a month. There were times that we would consider taking pick-ups in the past, and my point is we will not be doing that for the duration of this month, because the likelihood of encountering those players is now going to be fivefold (at least) from the current risk.
You also seem to be assuming, again from not carefully reading my post, that this is intended to target new players... period. I don't care if new players want to come to the server. Good, we need more people on Kronos. I don't care if they want to use the 7x exp boost that, admittedly, I dislike for a reason I'm about to go into. Good, they'll get their 60 in a timely manner they want so badly and left behind on their other server. What I DO care about is those people who will hit 60, not spend even a second thinking about going and polishing their gear up a bit, or farming some coin for their spells, which they can then use to go solo Scarlet Monastery or some quests that give decent gear for Level 50+ dungeons, and will instead IMMEDIATELY go to world chat and type "LFG BRD / Scholo / Strat / LBRS". I don't want those players in my parties, and I doubt you do either.
If someone is willing to take the time to get to 60, and then go make sure they're dungeon-ready, they're okay in my book, but again I'm not taking that chance during this month. About a week after, most everyone who took advantage of the boost should have had time to go tend to their gear and be dungeon-ready, at which point we will be ready to accept them into our dungeon groups.
