TinyURL and a several free alternatives have been known to do it for a while now. But, not everybody does this to be clear.
Running a free URL shortener costs time and money which is why they do it. For my URL shortening service https://blanq.io, I am planning to remove this feature and only support custom domains. Free shortening is highly abused by spam and its a daily battle to be one step ahead of them.
Last week, a single bad user created a phishing link and brought down the entire site for an hour until I was able to restore it.
