Reconnaissance
Reconnaissance is the newfag's excuse for showing up early to a raid. There is absolutely no need for reconnaissance before a raid. The idea of reconnaissance in real life is to scout out the enemy and return with information on what they are doing/planning so they can be prepared with a counter. On Habbo Hotel, there is absolutely no reason this should happen. It's not as though we don't know what's going on in Habbo before we get there.
When It's Acceptable
There's nothing wrong with being there early so long as you aren't causing a huge disturbance. Being early for a raid is only acceptable so long as the earlyfag is not currently raiding. This means he cannot be dressed as a nigra, nor can he be doing anything a nigra would be doing (blocking anything; flooding the room with a wall of text). It's only okay to do this anyway if your reason is to ensure that you will not be blocked out of the room. But when the raid starts, you must be in full nigra attire.
Why You Shouldn't Raid Early
Anonymous has power in numbers. After four years, the mods are pretty much aware of the "Pool's Closed" deal. Most mods, upon seeing a nigra, will IP permaban on sight. If you raid early, you will most certainly be banned and will not be there for the rest of the raid. Plus, being there early only alerts the mods early, ruining the whole fucking raid.
