So for the past week, everytime I look at my users online it shows me as the only registered user and between 5 and 10 guests. Half of those guests are from Russia and half of those are currently viewing the same page that doesn't even exist, but did once.
The topic of my site should be of no interest to 99.999% of Americans, and of completely no interest to anybody overseas. With all of these Russian visitors and so many of these visiting pages that no longer exist, should I assume these are all hackers or other bad people?
If I'm right to think these are evil doers, what actions should I consider if any? The only thing I can think of is a plugin that locks user accounts after a set number of login attempts. Any other actions I should take, if any at all.
