Hello,
I too got this comment. I’ve also had someone posting a couple of other comments that looked legit but were spam.
A really helpful site I’ve found is https://www.stopforumspam.com/. Although this is meant for forum administrators, I’ve found it really helpful in identifying possible spammers to my blog. Do a search on the IP address or username and see if there are any listings.
Here’s the one for this guy: https://www.stopforumspam.com/ipcheck/195.2.240.68. Notice the amount of activity (on forums) in the past day. They’ll set up a free webmail account, spam with it for like a day or two, and then create another one.
Obviously this site isn’t definitive by any means and mistakes can happen all the time, but a list of multiple entries concentrated on one or two days is at least suspicious for spam.
HTH,
Rainbow
