@Dronecatcher you could (ab)use Github releases to upload essentially unlimited files up to 2GBs each, just a suggestion.
Thanks, I do have my own cloud storage that I could link to but don't for security reasons - I use We Transfer for convenience and upload again if someone asks - although I do use Dropbox for stuff that I think warrants it.
Also, temporary links reflect the transitory nature of what I do - I've already stopped using Shapeshifter as it's buggy and not consistent.
Plus, I like to think when someone asks me for a file and I immediately give them the link, seven days is long enough for them to get the reply...
