> But I like this review of techniques, even the simplest ones are very effective, that surprised me.

because harvesters don't care until one technique gets massive use. if you come up with a unique but simple enough scheme for your sites and keep a few dozen email addresses out of their reach.. they've still gathered a million addresses. it's not really worth their effort to get the last 0.0001% of extra email addresses

so it's best to just not advertise your solution and make sure it doesn't get n any outside traction - if it gets popular the harvesters will defeat it
