Its very simple, if you do want to post a log, talk about everything in the first person. For example, Monty is installing ten 1000'ws, Monty finds it hard to keep temperatures under control, Monty needs information about something. The authorities can find out who you are in a second, but the question you should be asking is why would they want too, if they have no reason to believe you have a huge operation directly connected to you, they won't need to find out who you are. Fuck, it wouldn't be hard for some with tech expertise to find out your ip, your domain details and from there, probaly alot more. Its all about context. If you've given authorities enough reason to want to find out more about you, your fucked anyway.

Overgrow had a log system where when someone posted or connected to the site, the details of that connection would be stored temporarily and then automatically deleted after the connection had been terminated.
