It looks like Tizen developers are getting targeted for a spam scam. There are currently emails going out that pretend to be from our friends Appbackr, and claim to run a Tizen app contest. It includes an Appbackr office address in Palo Alto and email address and invites developers to submit their apps to Tizen.org
Going through the fine print it asks for $10 to be removed from the SPAM list.
This is definitely junk and you should report and delete it. If you have any further queries, then please contact appbackr directly at [email protected]
