by using the name from the input URL and not relying on possibly faulty

'userData[username]', if available, will still have the original name.
The metadata for Redgifs search results got stripped down to a bare
minimum, including download URLs. (Clicking on search results on the

As a workaround, we make an extra call to '/v1/gfycats/<ID>'
for each search result entry to fetch the missing data.
'/?&#' -> '/?#' and '?&#' -> '?#'
According to https://www.ietf.org/rfc/rfc3986.txt, URLs are
"organized hierarchically" by using "the slash ("/"), question
mark ("?"), and number sign ("#") characters to delimit components"
