Creating the report inappropriate content feature for mobile

You can use the http.request context object to get the parameters used on the request:

For example:

${http.request.parameters.name.get("page", 1)}

 One other thing you might want to look into is that there's a REST API method for reporting abuse. It's the "moderation/abuse/report" method in the Message class:

/restapi/vc/messages/id/1271/moderation/abuse/report

 I hope this helps!
