The following question might be a duplicate of the canonical question on serial voting. If so, feel free to close it. But I ask because it's not clear to me whether it's a duplicate question or not.
Sometimes I see a question or answer by a user which I like so much, I wander over to the user's page and scroll through their other questions / answers to see what else they've written. I click on the ones that look interesting and read them, and from time to time I upvote or (more rarely) downvote a question / answer which I find deserving. In practice, it's unusual for me to vote on more than 2-3 questions / answers from a single user in a session of doing this. Once I've visited a user's page in this way, it's unlikely that I'll ever return to their user page, and especially unlikely that I'll return to their page within the next few months. The intention of the whole business is not to give the user "extra rep", subverting the bounty system, nor to punish the user with spurious downvotes, but simply to expose myself to some of a good user's work on Stack Exchange.
Now, I'm pretty sure that this behavior is
entirely borderline appropriate on any Stack Exchange site. That is, there's some line between the kind of behavior I've described and vote manipulation, and I'm pretty sure that what I've described is well on the acceptable side. I imagine the actual threshold for vote manipulation is well slightly above the level of voting I've described.
Question: Is there anything else to be said about the kind of behavior I've described in the context of avoiding vote manipulation?
I understand that the voting fraud detection system never automatically punishes a user beyond reversing inappropriate votes -- any punishment for voting fraud is manual and would presumably only come about if there were a repeated problem, with ample warning and clarification on what's appropriate. I also understand the value in not being too precise publicly about what counts as "appropriate" and what doesn't to avoid the scenario of somebody trying to game the system and fly just barely under the radar in a vote manipulation campaign.
So I'm perfectly happy with the answer to my question being "No, just use your best judgment and don't be stupid; if it ever becomes a problem we'll talk about it then". I just thought I'd ask in case there is more to be said.
