Interpretation of MWD and DR regarding infidelity

[~ kd ~]

That sounds like an attempt to catch MWD at contradictory advice.

But, since keyloggers aren't available IRL, then it certainly is applicable to online affairs.

And, MWD does say gather evidence. She further goes on to say not to use that evidence to attempt to sway the AP.

So to me, the keyloggers or PIs or whatever are simply to gather information.

Towards the possible goal of learning what is appealing about the OP.
