From time to time, there are spammers who sign up and then post spammy spam spam. We do our best to nip them in the bud fast, but life has a habit of getting in the way.
Just as a reminder, if you look at a post and it doesn't make sense, like it doesn't really say anything or sounds like they don't know what day it is... it probably is. Don't click on any links. They may be phishing or something. On a PC, let the mouse pointer hover over the link without clicking on it. If you don't recognize it, don't click on it.
Not sure how to check links on mobile, but if in doubt, don't click.
Stay safe and stay cool, dudes.
