I am upvoting you because I like what you are doing. But I also see the point that @perennial and @rambai is making. They did not attack your main post but limit it to merely the comment. For that reason I think it is not personal. If you look at my previous posting, I am a regular contestant for music challenges and what you do can be wrongly interpreted as inviting the supporters of the participants to help you contribute towards the reward that you are giving. I fully appreciate what you do and like many others that organise contests they do spend their time, effort and even to a large extent their own money to fund it, I reiterate my point, I dont think they are personally attacking you but merely the reward system. I wish you well and please dont give up this good effort of yours.
