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

(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?
Oh boy... justusranvier is totally confusing the newbies.
