I also found it a bit disturbing that I could send my own
nodes to the front page. Wow! Talk about potential abuse!
I often wondered if that shouldn't have been addressed
awhile ago. I don't see people abuse that system, however...
There is at least one high-level user who regularly abuses
this system. He almost always frontpages his own nodes and
other root nodes which he makes an early reply to. It
happens too often to be a coincidence.
Observant monks know exactly who it is.
Hint: He always complains about downvotes too, imagine that!
