I guess, or understand, that 'receive' addresses can be safely used more than once?

Receive addresses should be used exactly one time, then never again.
If you reuse addresses for receiving bitcoins you have no financial privacy, and you're vulnerable to issues like this.

Oh bother. Thanks. In my case I have never used an android device for any Bitcoin stuff so I trust I am safe from the current non random number issue(?)
However, it has been convenient to gather occasional small amounts from the (get free bitcoins) site http://netlookup.se/free-bitcoins/247552
Just to be very clear here, I now should not offer the same receive address more than once then?

(edit)
I note that this site mentioned above works on the basis of a receive address being used repeatedly.... Is it a scam site? or is it just doing rather bad things?

If you are receiving miniscule amounts, then it doesn't matter. You can use common sense. The site isn't scam.
