Like Zappl and D.tube, whatever is posted on Parley.io will end up in the your blog section on Steemit. All activity ends up there.

Thus, any autovoters are going to upvote that...which is good unless you are posting 10 a day....which is easy to do in on a linking site.

That is what I meant by messes up the blog feed.

Nothing technical, just dumps it all in there.
