I have been experiencing periods of high load on my server. My host’s tech support department think that it’s because of spam post preview activity (see excerpt of email below). Is it possible for the maths capcha to be set up to work when both saving and previewing a post?
“When a guest tries to submit content they have to complete a simple equation to save the submission. They do not however have to complete it to then preview the submission. In my testing, the repeat POST requests from the previously mentioned IPs had almost identical log entries as my IP when I just hit the preview button.
Spamming the preview button on the forum is the best explanation to the load issue seen earlier, based on what information was in the logs.”
