Unfortunately, we found that the rumours are not rumours it is facts.
Quoting from the Original poster-
Dear friends, i have decided to post NO MORE petitions from yousign.org, petitionhub.org and yousignanimals.org.
Yousign.org is registered on a Romanian businessman, he is NOT an animal lover. The other two sites have the same layout and there are also the same petitions posted as on yousign.org. These two sites are registered to an address of the company domainsbyproxy.com.
