While I do not doubt that there are bots that access this forum, just as they access other forums, I don't think the image you show in your post necessarily represents a bot, or a human spammer or phisherman.  What are the signs you look at to decide that any member is a bot?

In my own experience with a different forum, a bot/spammer/phishing attempt is immediately recognizable by an initial post with links to entice someone into clicking it.

I have seen some more sophisticated attempts, where the spammer posts a couple of more or less legitimate posts, like commenting in a thread to look like a "normal" forum user, before casting out his hook.

But your screenshot doesn't really look suspicious, on its face.
