Uploading content shouldn’t be done carelessly. Take the case of Opie the Duck, here, who tried to post some random wheel to Derpibooru and was banned by Mod the Eagle.
 
Please. Make sure your uploads are properly cropped and tagged, relevant to the site in question, not absurdly gigantic, not a duplicate of an existing image, and are free of any sort of idiocy in the description box. This will ensure a pleasant experience for all.
 
This has been Sad Pony, local loser and content uploader, with a Derpibooru Public Service Announcement.
