Problem with domain on Twitter


My website is a sweepstakes/giveaway platform. I read through Twitter’s terms and rules and don’t see why our links are being blocked as spam and suspicious. Google diagnostics says our site is safe and there is no malware. Really would like to understand the issue so we can resolve it. I have submitted the link for review via Twitter’s form several times with no feedback at all.

Appreciate any one’s help since I haven’t had much luck figuring this out myself.

Thanks so much, means a lot to me
