If you take a look at archived pages for the domain, you’ll see that the few instances stored between 2016 and 2019 are practically void entries, displaying some sort of app for learning back in 2016, and moving on to blank pages from there on.
https://web.archive.org/web/20180107114232/http://www.lernmo.com/The Whois shows the domain exists from back in 2014, but it does not mean that their current owners have always been the same (as the archived pages suggest). The domain’s info last update is from the end of last month according to whois.
The link to their TOS does not display any content (not acceptable for an Exchange).
A good thing to search for, is any text of string from the legal part of the website (TOS, Privacy Agreement, Disclaimer, etc.). These are normally copy/pasted from another site, and often lead us to detect near-to type clones, such as is the case:
https://www.mareix.com/?AboutUs
The above is very similar, with a facelift on the landing page.
All in all, there’s no need to even waste any time looking into unknown Exchanges. If you need to use one, choose one of the top ones. If they offer to sell a shit token that nobody else sales, why even bother. Chances are you’re going to come-off scammed somehow…
