In the last few days, I've seen an unusual pattern in my rep: very many1 (more than usual) of my questions have received a single upvote (but only a few answers).
It could look like the votes of a sock puppet (it isn't). Could it be interpreted by the Stack Exchange team like that? Do I need to worry?
(Or are they from multiple locations?)
1 Number of unique upvotes = 28, by my counting (from 9 - 24 October)
