You could do it the normal way and post nudes, but where’s the fun in that? There are two ways to go about this:
1) Hack Tumblr accounts. That way you WILL make people follow you (which always leads to fame)
2) Go to your local supermarket. In the cereal aisle, look for the 14th box of cereal in the middle shelf. Once you’ve found it, look behind it and there should be a button. DON’T. PRESS. IT. Dear lord, whatever you do, do not press that button. Make someone ELSE press it, obviously. Do whatever you must to make that happen. I usually grab someone and say, “DON’T PRESS THE BUTTON” because reverse psychology is fun!
Once the button is pressed, it will dispatch an army of ninjas from above the ceiling tiles. Fight them all. Killing them is optional.
When that’s done, there will be news stories about it everywhere, but before they air or are published, rush home to your computer. Blog about the entire thing, embellishing when possible. “Some asshole hit a button I TOLD him/her not to hit and then I saved their sorry excuse of a life by fighting off a horde of trained ninjas.” You should gain followers instantly.
Option number two usually works better for most people, so I would try that first. If all else fails, just post your tits or dick and try to get famous that way.
