If I were in your position, I would accept the reward though not as the usual 50/50 but 100%SP. From the feedbaxk you got in just 3 hours in the middle of the night in the US, you can expect to get quite some response to that personal post. With some more SP gains, you can then go ahead and reward other people more, which seems like a thing you would likely do.
Even though I am very new to Steemit, I am very interested now in what you have to say about yourself. Actually I stumbled over this post when clearing my "following" list when going through my homefeed, having had to many posts that werent interesting for me. But you definitely ignited an interest for you in me, even without making any factual statements but just by showing how much you reflect and contemplate on your actions. I would definitely like to know more about you! And I dont see anything wrong with getting rewards for that, especially when you can make you accoubt more valuable by this and give some minnows or generally other contentcreators just a couple cents more to their articles with your upvote!
