No this isn't clickbait or false rumors like 100% of the stuff you find on the internet. One of the Producers yesterday said a season 3 was coming soon, and just today the studio has confirmed they're in development of a season 3 soon. I'm so glad! and I hope once the anime is made and released in Japan, that Funimation gets the licence for it and releases it over here.
I wouldn't get too excited yet, since even the producer himself says this was extremely unofficial. What we got was a "please wait a little longer for season 3!" That could mean that they want to do it but are having problems in other areas (funding for example). I'll get excited when I hear a "We've started".
