Bogus forum posts (phishing)

I have recently noticed a couple off-topic posts to the "ContextCapture Descartes Pointools" forum that appear to be bogus questions. Within a few days someone else responds with an answer that involves a link to an external website. I feel that these are phishing attempts, hoping people will click on the links. 

Neither the person asking the question, nor the person providing the link to the website for an answer, have prior activity on the Bentley Community Forums.

Here are the forums posts I noticed.

What is the recommended process to notify forum moderators about this type of activity?

Thanks,
Ron
