Well, in my opinion, the main reason for this is the restriction of '30 participations before you can post' that the website oblidge, which leaves new members with no other choice but to post those "thank you" comments

I did not post one thank you message, and here i am.
There are many alternative options to reply to a post: correction, addition, question, answer, critic, opinion, ... Likewise the post is beneficial to every body and not boring as when crowded with lazy replies (thanks).
