Last week I set up a forum category for an RSS feed for scam emails. The forum has 4 child forums that catorgorize the format of each scam email.
About 100-150 new threads are made a day, each thread being a scammer email found across the internet.
Until today those particular forums (the 4 child forums) were only getting about 5-10 search bots on them in total, but then I decided to change the forum description to show what child forums were inside, check this image so you can see what I mean:
Almost immediately after I did that, I get 50-100 search bots going through them. Sometimes up to 150-200.
Is this coincidence, or to the search engine spiders like to see the links beneath the forum descriptions?
