I got another survey invite today - I have been getting them periodically. I decided to check it out. I clicked forgot password, they sent me a password. You have to do a captcha, sometimes you can't see the bottom of it and it will say it is wrong, so you may have to do several before you get it right.
I clicked to fill in my profile, They already had my name, birth date, and address, state and zip code. The question about household incomes are in another currency so I put perferr not to answer.
I'm thinking maybe some old site that went out of business was bought by them or merged with them and maybe that's how they got my info. When filling in other parts of the profile then hitting save the yes no buttons are in Chinese or Japanese, I took a chance and hit the first button and it turned out to be the Yes button. I did 1 survey and got 5 dq points.
I think I will try it for a while but if a lot of it are in another language I will stop.
