Wondering what is LXJS? LXJS is a 2-day not-for-profit by-the-community and for-the-community international conference about the New Worlds of JavaScript.
It's rather suspicious that LXJS tickets are being offered on ti.to, not on LXJS's own domain, lxjs.org. And LXJS's own site claims that early bird tickets are sold out:
Also, note that the 2014 conference is in Lisbon, Portugal.
LXJS is one of the founding partners of ti.to (you can check the our logo here: https://ti.to/home) If you go to LXJS.org webpage, you will see that the ti.to link to the ticket sell is the same :)
Never the less, your question is very pertinent! thank you!
