Thanks. Note that "nodes you (the human) wrote" says nothing about user accounts. If you upvote nodes you wrote — however you manage to do so — that is contrary to the spirit of PerlMonks.
Imagine if, for example, sundial started posting anonymously and then using his account to upvote each of those, to try to offset the negativity they'd inevitably attract, that would be an abuse.
Again, we're just looking for large-scale, systematic abuses. One or two here and there is not something we'd be concerned about.
