Web 2.0 creation, must fill in profiles?

is it a must to fill out your account profiles for the web 2.0 or can you get away with not filling it out?

If you don't fill out your profile, your web 2.0 properties stand a higher chance of being deleted due to spam.

Exactly as said above, make it seem like a real profile. Create it, fill in the information, and then wait a few days until it is approved before uploading articles.

Depends on the web 2.0 platform.

I usually don't fill out the profiles, and I lose about 10% of my accounts every 3 months.

I would probably lose 5% only if I filled out the profiles - or it might make no difference at all. I have so many that its not worth the effort for all of them, so that's why I don't do it when I am manually signing up.
