Your link says "Ask Me Anything" so I'm taking that at face value, because I'm really curious why you're looking for donations on a free social networking site that you repost other people's work on. Just, sort of a question I have. If there's a legitimate reason that's cool but... without an explanation it looks pretty sketchy.
first, you need to remember that clicking on the link and donating anything at all is entirely voluntary.
Regardless of whether the site is free or the work I'm sharing is my own (and remember, I link to the original source whenever possible), it does take time to aggregate the posts that end up here.
Also, as I haven't done more than put the link into the theme script & make exactly one post about it (not counting the two asks I've gotten about it), I haven't done anything to really "seek out" donations, so one could reasonably argue that I'm not actually 'looking for donations' as much as you seem to think. :)
