As far as I know, I think there are online portals where the social issue can be reported and addressed. Social issues are problems within society, and they keep increasing on a daily basis. While I'm not so sure of an online portal that can address all social issues, but I'm sure of the fact that there are social issues websites that are meant to be used by people to address different kinds of social issues that have to do with what the website is all about.
For example, there is an online portal where people can learn and address social issues that pertain to their fundamental rights as human beings. If you want to know more about the website, you can simply visit https://www.pdhre.org. Also, there is another website where social issues that pertain to child abuse and child labor. To visit this site, simply go to https://www.child-abuse.com. On child labor, you can simply go to https://www.aft.org/news/call-action-end-child-labor-us.
