I personally wouldn't do that, as dumping 50 Merit on a Newbie's post doesn't seem right to me.
What if higher rank member receive 50 merits merits for a post,Is it okay?
I think we need to serve the merit based on quality no matter of newbie or legendary.
On top of that, my "personal" sMerit pile is higher than ever.
Pour some of them on me. 
I am not begging here
