Sorry for the reddit copy/paste. I'm hoping to find more participants, should've posted it here earlier too:
Why: I can never find a straight answer or solid confirmation about receiving humanity from upvoted messages. I had a message get a +1 rating, and I'm pretty sure I didn't receive a humanity. I once read that you needed a +3 rating before you start getting humanity, or it's possibly one humanity for every 3 upvotes, but this hasn't been confirmed either. If we have a coordinating upvoting session, we can perhaps get to the bottom of this.
Where: Anywhere on the bridge before Ceaseless Discharge, or right by the CD fog gate. It's not the most highly trafficked area, so I figure it's a good spot. It's not a long walk from the Daughter of Chaos bonfire (warp).
When: Tonight, 9PM EST.
Instructions: Leave just one message, that says "Humanity?". I know it'll be tempting to spam, but if it takes multiple ratings to receive humanity, it'll be easier to keep track of the ratings of one message. Try and be between the levels of 80 - 120. Run back and forth, hang out for a bit and upvote every message you encounter.
Post here when you leave your message, and share your level and system.
SL100 is preferred, because it's a common level and I think (just a guess) that messages may be limited to co-op range. Players 80 through 120 will be part of that group, if that's correct.
And don't forget to not already have 99 humanity on you. Kindle some bonfires or suicide and reverse hollow if you're already maxed out.
