This is something I just found in my email backups of the 90’s, when ADSL wasn’t available as today. Replace “mailing lists” with “the Internet” and it still makes sense in these times of attacks to Net Neutrality:
...please do NOT send to public mailing lists messages with fancy GIF backgrounds, stilish business cards, etc... This practice doesn't provide any additional information, and only wastes bandwidth. Besides, if I wanted to be brainwashed by nice pictures, trendy music and off-topic animations, I'd rather turn on my TV, not my modem
