They're just troll/spam accounts that for some reason have now adopted a strategy of posts that are just as poorly written as the previous I-hate-XMR posts but are now I-love-XMR. Why they are doing this (other than increasing post count) I have no idea.
They start accounts, to post 14 posts every 2 weeks ad after few weeks when they become full members sell them. Because of signature campaigns where higher your rank is more you are paid for a post, accounts get nice prices. Easiest is to post in altcoins and speculations threads, where you can easily be at least tiny bit on topic.
So best is to not to take so serious accounts under 50 activities.
