Extraterrestrials care not about speech. According to my lackey, the Internet is serious business for humans.
Professor Wiio says;
If a message can be interpreted in several ways, it will be interpreted in a manner that maximizes the damage.
Limit or boost virality and damage by self destructing the source of an imagined controversy. This is not to be indexed — search engine bots shall not pass (hopefully), neither should this message propogate through any feeds. This hidden message will only disappear in my timeline because I’m an intergalactic time traveler.
