I'm just going to share a few thoughts on what I'm going to call "Showderp Etiquette". Not a strict set of rules, but some guidelines to keep the thread fresh and to let everyone have fun.
First of all, don't spam the chat. That doesn't mean you can't use the usual Showderp lingo, it means 'don't cuntpaste the same word or phrase over and over'. It's more likely to irritate your fellow Showderpers than the opponent. Don't spam the lobby chat either, because you're just going to lead the mods to us.
In the same vein - and this should really go without saying - DON'T FUCKING MENTION /vp/ OR SHOWDERP. This isn't just because of 'muh sekrit club' or 'muh chan culture', it's because we've gotten into shit with the Showdown mods before; people have gotten banned and we don't need it happening again. If someone asks why there are so many people in the chat, the usual cover story is that the champ is Marriland. Stick with that.
Don't hog the champ spot. We don't care if you're 'on a roll' or if that last match was 'bullshit'. A good point to call for a new champ is after around fifteen battles (not including opponents who instantly d/c), with a new team every five or so.
Champs and spectators: show some mutual respect. Champs, don't bitch and moan about the shitty team you have to work with, Spectators, don't give the champ hell for losing if we give him shitty Pokémon.
When a new team is called for, try to suggest something fairly original. The 'classic' Showderp 'mons like Boom Boom, Blood Ernie/Totem, Waifu, etc. should be a rare treat, so constantly having a team with more than one or two of them somewhat defeats the purpose.
It's been suggested that we instate a "no repeats" rule, where no Pokémon from the previous team (or from within a certain timeframe) can be on a new one, but others have said that it would be too limiting/break the flow of the thread. Personally, I haven't made up my mind yet.
