I want to preface this post by saying that I think it's wrong to send merit to your own alt account. We can't merit our own posts (I think, I've never tried) so we shouldn't be meriting our own posts regardless of how many accounts we use to make posts.
But, is this really merit abuse? I haven't spent any time digging into the post that was sent 2 merits (it's been deleted and I don't have the time right now,) but I found something interesting about
this post that was sent one merit:
Two days after philipma1957 made that post using his alt account, someone made a post questioning whether that was really philipma1957 or a scammer:
~
Are you seriously using a different account for your cell phone or are you a scammer?
If the former, WTF.
In the matter of 1 minute and 50 seconds philipma1957 sent 4 merits in that post, one each, as you can see here:

And this post confirms what I originally suspected:
basically the cellphone is used to prevent a crowbar attack when I drive around
and the laptop is used to prevent a crowbar attack when I go to the farm in Clifton
I just gave the cellphone account a merit to confirm it is me.
