One reason to not allow animated images is that the file size for these images can grow large very quickly, another is that we have to consider people visiting the forums through e.g. mobile connections to the forums: both in terms of content (size) to download for them, as well as loading speeds. The latter is of course also applicable to people who visit our forums through slower internet connections. Yet another reason is that (too) many animated images can make the forums look an 80s disco look pale in comparison. But, as with everything in the forum rules: we have the rules to have a basis to work with. That doesn't mean we apply them to the letter. In applying the rules to the forums, we first and foremost apply common sense to these rules. What exactly the limits of how far they can bend are, we cannot say; that is partly the subjective nature of forum moderation. It very much depends on the situation/context as well. I hope that what I wrote still makes sense. If not, please do feel free to ask your questions so that I can explain what I mean in a bit more detail.
