I mostly agree... I used to work for a classic car website, and in that case, we dealt with a LOT of comment spam, and scams that were out there. A lot of it is actually individual people, doing actual work to get past. We also did see a lot of custom bots, etc. It took a few different approaches and even recaptcha wasn't always the best option, but it did help with most of the non-scam traffic.
