If your methods are able to be replicated than how could one be skeptic. Sometimes, the best defense against skepticism is concise clarity. If you can prove yourself in the size of a tweet you might be believed. Any longer than a tweet, it doesn't really matter how good what you have to say is, some people just won't hear it. I know. The most intelligent person I know cannot pay attention to me longer than a tweet.
This is good for someone with a repeatable demonstrable claim. However, in many cases, experiences aren't necessarily repeatable due to unknown conditions, or a failure to understand what exactly happened or why. Also: sometimes proofs may take a long explanation. So 140/280 characters may not be enough (see various scientific studies that are longer than a tweet).
But if a time traveler claims to have a machine, and can't provide a photograph or video of the machine, that's pretty much a death sentence for their claim.
