One step would be to choose which subreddit to put our plea into. Reddit is divided into thousands of subcategories, some of which are well suited for us. The first to come to mind would be
http://www.reddit.com/r/IAmA/ , or IAmA. Stands for "I am a" and is mean to be the prefix to your post, so for example our post could be titled "IAmA man who is allergic to my own semen" or "IAmA man who orgasams, and then feels like I just jizzed my brains out for days (I have Post Orgasmic Illness Syndrome"
Note the ridiculousness of the second suggestion. Take a look at the most "upvoted" or highest viewed posts, and they have very witty/provocative headings. One problem with that subreddit is that it is in the singular "I" rather than the "we" that would suit a general plea on behalf of everyone. But that's a relatively small thing.
There are more subreddits, probably one for charity, but these smaller subreddits don't go nearly as viral as the others. Explore the site, lets get some ideas!
Oh and feel free to write some content for our reddit post and post it here, we are going to need to fine tune it
Here's one that got a ton of attention: "IAmA guy that hasn't pooped in the month of August yet. Ask me anything about my extreme constipation."
