I noticed that for the last couple of weeks, most of the questions get between 15-50 visits. But two recent, non-sequential questions suddenly have more than 500 visits. The votes are not correspondingly high. What is the cause of these spikes? Could it be bots based on key words?
The two questions I reference are:
How to programmatically distinguish European from non European call sign? with over 600 views
What might this tower be used for? with over 500 visits.
