Nothing a spammer does surprises me.

For anyone interested, there are some very good instrument simulations for training purposes online. Two of them are:

Tim's Air Navigation Simulator (this has been around for a long time and has multiple options)
and
Holding Quiz (this is primarily a VOR holding entry tool. If you uncheck "North is up", "Show diagram" depicts the hold in relation to the DG - very helpful for helping pilots whose brains work that way to learn to use the DG to visualize the hold)
