About the mod itself (skinchanger.cs), judging by the comments I've read here and in other topics, I've made a mistake in allowing it. When Mia asked me, I just thought "Sure, she wants to use a fast skin as a female, why not". She already has access to fast skins as a VIP, so I didn't think it would give here any more advantages. Now, I didn't take into account a lot of factors, such as that it might be misleading, her skin shouldn't be moving like that in the first place. Secondly, I didn't take into account the consequences it would have if a non-VIP or a pres/vice would be using it. They don't have access to fast skins, so they would be getting an advantage out of it. That means only some people would be able to use the mod, and we'd have to create rules specifically for when you can/cannot use this mod. If we start having rules for each specific mod, we'll end up with a 20 page rule list, which will only bring more confusion. Another mistake was not informing people that we allowed this mod, I agree that if we allow something, everyone should be aware of it so they can use it themselves as well. So yes, I made a lot of mistakes in this case, and I want to apologise for that.
Now, taking into account these factors, and judging by the responses we got about this mod, we're disallowing this mod. As some people pointed out, it does give an advantage when you use it with a smaller skin than most fast skins and the skin doesn't move as you expect it to move, but I don't think these advantages are very significant. Another reason we're disallowing it, is so we don't have to make specific rules for each mod, so we can give a clear answer. So, from now on, skinchanger.cs is no longer allowed. Again, we're not going to straight up ban people for it, we'll warn them to remove the mod first, so they're aware of this change and have a chance to remove it. Only when they ignore these warnings, we'll move onto punishing people for it. Also, as I said before, we're not going to punish people retroactively for it either, Mia asked me, I allowed it, so I'm not going to punish her for something I allowed.
One other thing, as some people pointed out already, having smaller skins on the client side shouldn't have any effect on hitting them anymore. Since we've introduced the weapon-config, the damage of most weapons (including all bullet weapons), depends on the shooter. So, if you hit their skin in your screen, they will receive that damage.
Now, as I said before, people ask us if mod x or y is allowed all the time, and up until now, we didn't really have a clear process for it. We'd just look into it, and let them know if it's allowed or not. We do have a topic for such questions, but that turned into a mess pretty quickly, with unanswered questions and no clear overview of things. As this situation has pointed out, this isn't working. Only the players who ask will know if a mod is allowed or not, and depending on who they ask, they might get a different answer. So to prevent this from happening in the future, we'll do the following. We'll make a sub-board under the Suggestions section, where you can ask if a certain mod is allowed or not. Every mod will have it's own topic, and once we allow/disallow it, we'll add a tag in the title (for example "[Not allowed]Fastped.cs"). That way, by browsing the board, you'll get a quick and clear overview of which mods are allowed or not. That also allows everyone to give their opinion on why something should be allowed or not allowed, or provide more insights we might not have. This will be the official and only way to ask if a mod is allowed or not (including for admins). If you ask a staff member about a mod, they'll forward you to that section.
