In the comments to this question I advised that giving a full answer to a HW&E question is not what we should do.
The question which contains nothing of conceptual value, is clearly a HW question and isn't well formatted, appears eligible for 'close' votes (but I haven't voted to close yet).
After my advice to the member providing the answer the member then asked for upvotes. Per se there may be nothing wrong with a bit of self-promotion but is it really acceptable? And what would happen to any upvotes if the question was closed later anyway?
