I do too but Marky is right when you look at shorter comments. It does look a bit ridiculous. Look at this post and comes of the comments where there are a few one line comments in a row. You see the Leofinance beta listed a number of times.
Posts are obviously a lot longer so it does make it less "spammy".
Of course, it wouldnt be as much of an issue if everyone left comments of a few dozen words in length each. LOL

It also builds a spammy link profile when it comes to SEO. When each page has 20-50+ backlinks to itself, it also weakens the link juice a page can give.
