I saw all those what a pain in the ass. Hopefully you don't get more. The website I built for my workplace was getting hit numerous times a day so had to end up putting a captcha for every comment made to stop the spam coming through. Annoying much?!
I did warn them and deleted their posts.
It was a flood of posts with no external links, all in an asian typo.
I don't know how to find their profiles since i deleted all their posts.
They've been new members friday and saturday, if you have access to a members' list.
