Hi This is LimLims from bitcointalk

So this a Pure Way of Scamming.

I checked the Deposit section of Nitrogensports and as mentioned in the Post above by the OP in the blog no such notification was not there.

About the Promotion the the Nitrogensports team hasn't mentioned in their official blog also https://blog.nitrogensports.eu/promotions/

Neither in their ANN thread in the forum. https://bitcointalk.org/index.php?topic=355081.0

So it's an obvious scam attempt which will be done if we add that extension in our Broswer, it might just take all our balance that we will deposit in the site (not tried though).

I have already reported the user to Mods, but for the time Being as the OP's thread is locked, it's a request to DT to tag the account.( https://bitcointalk.org/index.php?action=profile;u=2869754 )

Atleast someone will be saved from being scammed.
