you can upload any file below 25mb for free unless it's malware, it's a direct link that works everywhere, and it's quick because you always have discord open. if it's something not too important why wouldn't you?

I mean, you probably don't go and unplug your modem when you get done with a browsing session right? Or turn off your phone when you aren't actively engaged in a phone call?/writing a text message?
