What really drove me to asking this is the fact that when I logged into my SO account yesterday, I was dazed/amazed/confused to see that my reputation sky-rocketed by 200 points since the previous log in. (It was 595 before and when I logged in again it was 795). Then last night, 195 reputation was reversed for serial upvoting.
Now to get to that kinda position here requires many upvotes to an answer or a question which none of mine have. I went through this http://blog.stackoverflow.com/2008/12/vote-fraud-and-you/ and Are serial upvotes detected? And some more questions on meta.stackoverflow.com that deal with the same.
Now my question here is how do I save my posts from being serially-upvoted? I completely understand that SO does have employ heuristics in order to detect the same. But the thing is this, I really don't want people here to sky-rocket me through serial-upvoting and then the SO tracking system very aptly and cleverly detecting the same and negating those points. But if it's genuine that some 10-20+ users really found my answers proper then it should be fine.
