Rev, you have already stated that you do pay tax on your main wage, but aren't going to trouble the taxman with your nocturnal earnings.
Is your scenario a similar situation ?
I'm sure that there have been quite a few of us on here who, having paid a substantial amount on our main wage are quite happy to keep 'a little tickle' for ourselves..........However, I would be concerned that doing so regularly for quite large amounts could come back to bite me on the ar$e.
So, I suppose my answer would be 'yes, but not for much and not for long'............:o)
Am I going to Hell ???
