When I get bored I browse through the comment spam on my WP blog. It quite amusing.
So remember the old "Submit your URL to 1500 search engines" spam we used to get by email? Well recently I got comment spammed to "Submit your URL to 2500 search engines". 1. Here +20 years later and with Google as the only search engine this spammy pitch is still making the rounds, 2. the alleged number of search engines is now at 2500 so we have search engine inflation.
It was interesting seeing this old old spam still making a rare appearance as a blast from the past. Some others like time shares seem to have completely died out.
