I expect you're probably seeing downvotes on your node. That's because of this widely held voting tenet:
- If the node talks about voting, -- the node.
Within the category of "nodes about voting", nodes that actually complain about being downvoted get downvoted the most. I don't think your node will suffer as bad as one of those, but I've seen a lot of nodes about voting get low reps and I've seen references to this trend in a few nodes and Chatterbox exchanges.
I guess now that my node is probably due for some downvotes, since it's talking about voting too.
