I also have to emphasize this point. There are many instances where the same user makes the forums a more difficult place to assimilate into for everyone. They also do not get any repercussions for their actions other than a reason why their first post was invalid, in other words there can't be warning points given for stupidity. I'm not calling out anyone specifically because the truth is there are multiple people that I can think of that are like this on the forums, whether it be in the past or present.
This is also key. It's difficult for a new mod to become familiar with the community, especially if they have been a regular player for a short amount of time. Also, not too many experienced players want to even become mods in the first place because they feel as if they will lose connection with the normal players, and be seen as a "higher-up" or "oh shit this guy's here i better try to not get muted". This is the nature of moderation, but I feel as if it should be more of an inviting thing. Mod bias is also a huge issue within Pokemmo. I can think of many moderators that aren't particularity liked by the general community at the moment, and this is again derived from the fact that many people do not know who they are/were before they became a mod.
