But what you said above is interesting, for you the acceptable limit of a shortened address should be 10 characters at least.

I see no point in shortening anything. It requires trusting a third party, while I'm using Bitcoin so I don't have to.

Address strings shorter than that are such risky? I mean 7+ characters is not enough according to you? Are there some figure (stastistics) about that somewhere?

I did a quick check of currently funded addresses. These are the most common "firstbits":

I think many of them are burn addresses, but that can be done to any other "firstbit" address too.
