Presumably from RR.
I don't know about here, but I always felt that on RR the forums were where the writers spent time hanging out and talking rather than the readers.
Your signature is too big. Any signature that is too big hurts the eyes and therefore give other users an extra incentive to disable signature viewing. This would hurt other authors who also use their signatures to promote their stories. The mods have been laxed in moderating signatures because they understand that authors do use it for promotion. Just don't make it too big and cause trouble for the rest of us.
As it is, your signature is 2000px wide and 1000px high. As you can see, most people show thumbnails of their cover instead of a extra size banner. You can get the thumbnail of your books by going to the main site, clicking 'Create' and copy-pasting the image link of the images there.
From 'Other' in Forum Rules:
No Videos and GIF's in your signature
unless under a spoiler.
Picture in signature should not be bigger than 200 px in height.
Total height of your signature should not exceed 15 lines of 15px text.
Also, while it's not against the rules, why is your only promotional link point to the book outside the site when you have the book on this site? There have been people on novelupdates banned for that because he kept doing it despite being informed not to take advantage of the laxed moderation. While it's not in the rules yet, it can be made. Don't know if RR has such rule now, but there was a time when RR didn't allow linking out of the site.
