Why do spiders do this?

I know my forum is new, and probably is not worth the spiders attention, but I try to create daily content, and add new articles weekly, and from time to time I see
mr google, yahoo, some spider99, and some spider it looks like it
would be from overseas. They come, they go...

now, why is it they come and go fairly quickly, but yet when I
run across some old inactive forum, well, the only member
activity they seem to have is spiders, and no matter what
time of day you go there, you will see spiders on the forum...

I would love to have an active forum with little spiders
rather then a dead forum with 25 spiders....


Whats going on with this?

As you have more content and more frequent changes, they will stay on longer. As you get better indexed, the bots will go out to check for updates. Things just don't happen over night, and bots are 100% out of anyones control bot the bot owner.

that I understand..but why are bots all over dead forums?
its not like they havent seen the content million times
already...dead forums maybe get a post here and there, but
not the need for a bot to stay on the forum day and night,
this is what I do not get.

even a dead forum appears different to bots.

today/yesterday turns into a date
brithdays change
etc etc

the page has different code on it
