You're going to be seeing a LOOOOOT of upload spam from me here for the next while out of preparation for deviantART Eclipse potentially completely self-destructing the website. You can learn more here: http://fav.me/ddxhwf0
I have over 3500 posts on deviantART that need to be re-uploaded. If I did so in a scheduled, not-spammy way it would take years. XD
You can just have it set to post once every 30 minutes or an hour apart. It gets really REALLY awful for all the other artists and the community when someone uploads a crazy amount of content all at the same time. Spreading out your uploads will help the community as to not flood out other people's content.

Gonna drop this here so that you can schedule the Spam so it is less spammy, and so that you don't have to pay attention to it that much after setting up the scheduling.
