Its funny and most of the times frstruating to watch the 'splog trend'. I've been working with splogs so much that just by seeing the title and the url, I can accurately predict whether a blog is splog or not!

Also, everyday, I see funny trends in splogs.
Like on certain days, there would be very less number of splogs or no splogs at all or the opposite. Sometimes I see a special group of splogs that I'd like to call 'celebrity spam'

That'd be "Bradd Pitt, brad-pitt.blogspot.com/brad-pitt1", blogs with junk contents and dozens of them focusing on different celebrities. Now I've added an automated filtering techic that completely filters out celebrity spam. This is obviously done by one person or a group of connected persons.
And what ever the trend is, blogs on the subjects 'Weight loss, Pills, Investment/Insurance, Dieting..' tops the charts. Among this, weightloss is the worst. I've seen a lot of people justify their spam blogs, but the funny thing is that Why in the world is everybody starting a new 'Weight loss' blog crammed with ads!
Then comes the adult blogs. I haven't seem much adult splogs, but 99% of the adult blogs being submitted are just pics and no content :| Verdict: blacklist.
What these sploggers dont realise is that they wont anything but hatred (I hate to say that). I haven't heard of any splogger who has become a millionaire by cramming adsense and spamming directories and all.
And finally, I'm really happy to see a lot of people writing on subjects like 'Weight loss, Quit smoking, Clear debts..' crammed with adsense ads. Its really interesting to see these people's willingness to provide valuable information and help to others :| (When is this going to end
