The absolute maximum filesize limit is 1MB (1024KB). This is also for the entire signature, not just individual files. Stuff within spoiler tags do not count towards the size limits, but do count towards the filesize Limit. The filesize and size limits are not TARGETS, they are the absolute maximum you're allowed. Stepping even slightly over is against the rules.
Animated anime scenes are pretty but not everyone wants to wait for twenty megabytes worth of them to open a page. Being considerate about this will help with loading times and make the Forum much smoother to browse. If you have too many signatures we will tell you to remove it or a staff member will have to remove it personally. Repeated signature violations will lead to a signature ban.
Any type of pornography is prohibited in avatars and signatures. Anything sexually explicit but not pornographic must be placed under spoiler tags. Other inappropriate images which include racism, flaming/flamebaiting, etc. will also be removed or spoiler tagged. Seizure images are not allowed on NarutoForums, this includes signatures and avatars. All avatars and signatures are subject to censorship upon the discretion of the staff if the staff deems your signature as inappropriate.
