Can you advice me short url services of these types: 1. Can generate different urls for one my url. Such as droiop.com For example I give it domain.net/post1.html every time and it generates me different tags like droiop.com/tag1, droiop.com/tag2, droiop.com/tag333, etc. - each time new tag (or sub-domain) 2. Don't have button/link "spam abuse" or "spam report" on main page. I mean there must be difficult to write abuse on my short urls to admin/owner of service. It will be better if any service have all these 2 points.
