With Comprehensive guide to mining testnet ether there were 3 close votes for it being off-topic. It's hard to understand why it would not be on-topic. How should it be dealt with? Some options:
I would say remain as is. While I see that the question is not very specific, it's very well on-topic and an actual issue the users faces.
In general, I think it's good to have frequently asked questions featured on Stack Exchange. This could be a good example for a canonical question on how to get testnet ether with all options available and strings attached.
Finally, I don't think we should convert it to a community wiki post unless the author wants to.
As a matter of emerging policy, the Community Wiki setting has been all but deprecated. A user's answer should virtually never be forced to Wiki (to remove reputation or otherwise) unless it is explicitly set or requested by the author, and the ability to mark a question Community Wiki (with all its answer) has already been removed.
