Four tasks that belong on a schedule sorted by frequency precisely because their frequency is zero. Each is categorical, which makes them the easiest entries here to follow and the ones people most often talk themselves out of.
Osiris addresses
Three published addresses for the same market. Copy rather than retype.
This list is published, not monitored. An address that opens is not an address that is genuine, and the check that settles it belongs to the every time list.
Why categorical rules are easier to keep
A rule with an exception requires you to assess whether this is the exception, and assessment is exactly what pressure attacks. A rule with no exception requires nothing of you in the moment, which is why it survives situations that judgement does not.
That is the whole argument for this section. Not that these four are the most dangerous things on the site, but that they are the four where a flat answer works and a considered one fails.
What they have in commonThree of the four have somebody on the other end arguing the case, and the argument is always reasonable sounding. That is what a good argument for a bad action looks like.
