Its the marriott Pulse surveys. they take forever to post so they may be from surveys you did a while back. Speaking of which there was a survey a couple days ago, which i forgot to post about it. for those signed up, you may want to check out the site. it was about dinning and social media.
Huh! we'll have to look into this "Marriott Community Standards". It could be survey like the others mentioned. Do you mind sending me a private message with your Rewards number, doddsy69? We may be able to find out what this is with that info. Thanks!
