I replied to your claim that base64 should be preferred over "foo at bar dot com" since it would be "unlikely to be automatically checked by bots". I find that claim unlikely since a scraper that is adjusted to handle the former will easily be adapted to the latter and likely already is today.
I'm happy to hear a counterargument to that position, but please don't include an insult.
Since offering emails in base64 form is not usually done, I consider it pretty unlikely that bots have been specially modified to go around checking everything which looks like base64 to check whether them codes have an email inside.
If you don't want people to be insulting, maybe you should think through your arguments more carefully before treating someone else like the idiot.
