Hi Matt the button doesn't work. It's grayed out. Tried with different browsers and even mobile. Just doesn't work. Please fix it. Thanks

As many of you know, last year Adobe Stock launched a free collection to drive traffic to the marketplace. The initial collection was limited to participation from a very small number of Adobe Stock Contributors. We were pleased with the results: traffic did increase and many visitors who initially came for free content converted to paying customers, resulting in added revenue for the larger Contributor community.   

It�s now time to refresh and expand the program. For a limited time starting on June 7, many of you will see a banner in the dashboard section of the Adobe Stock Contributor portal. The banner gives you the opportunity to nominate qualified photos from your portfolio. You can nominate all eligible files (photos only at this time), or you can go through the Dashboard and nominate individual files. Please note that your best-selling images are exempt from this program. We will not be accepting any images that received more than 4 downloads in the past 12 months.   

You have until June 23 to nominate any or all your eligible files. After that, the banner will go away, and our moderation team will quickly review the submissions.   

A big difference between the Adobe Stock free collection and other sites offering content for free is that we are paying Contributors up front for participation. For every file approved for the free collection, we are paying a one-time rate of $5 (If paid in USD currently. Otherwise, 5 credits in your currency) . This payment is for 12 months of non-exclusive use in the free collection. After the 12 months are up, the files will automatically be returned into your paid collection. 
Please see the FAQ for more details, and let me know if you have any additional questions not covered there.

Thank you,

Just got the same email:

We have become aware that your portfolio now includes titles with spammy repetitive words or phrases. Repetitive titles like �orange, orange, orange� and �icon arrow, icon arrow, icon arrow� create a poor customer experience, and are prohibited under our metadata guidelines. These titles are considered spam and are not accepted for publishing during the review process. Editing them in this manner after your content has been published is not allowed.

You are now required to edit these titles to bring them back into compliance. In the coming weeks, we will review our collection again. If you do not correct your titles, or you continue to create repetitive or spammy titles, your account may be suspended.

First it's really sad, but not surprising to see how much they care about us: they don't care at all... They threaten to close the account as if we were just numbers (which is somehow true but we pay their salaries so please show respect).
Second you can notice the same list of spammy words that some of you got, which of course I never used.... Seems like they are running a software and it messed up something.... Glad I'm not the only one getting the email... But I honestly don't know what to do... I emailed them... Let's see if they reply...
