I frequently read other's answers by topics and I have a list of users who usually give hight-quality answers I would like to read in some topic. It is totally possible that I would read (more than) 10 (new or old) answers from a same person in some single day.

I would certainly like to upvote answers I think are useful after I carefully read them in details. But it seems that if I upvote a single user too often, the system would take it as "serial upvoting" and reverse it.

Here are my questions:

How many upvotes are to many? If I write a comment to every answer upvoted about why I think it good, would the system not reverse my votes then?
