Enlarge By Charlie Nye, Indianapolis Star Attorney Mark Zuckerberg receives about 500 Facebook friend requests a day, most mistaking him for Facebook's Mark Zuckerberg.

This 48-year-old bankruptcy lawyer from Indianapolis shares a first and last name with Mark E. Zuckerberg, the 26-year-old founder of Facebook and the subject of the new movie The Social Network.

It's a coincidence that has led to a lot of confusion and headaches for S. Zuckerberg, mainly because Mark Zuckerberg is an unusual name. Only a handful of people in the country have it if websites like www.howmanyofme.com are to be believed.

Besides, Mark E. Zuckerberg is notorious.

Not only did he create one of the most popular websites in the world and change the way people and businesses connect and communicate, perhaps forever. But he made millions of people really, really mad.

Earlier this year, he led changes at Facebook that many of its 500 million users said violated their privacy.

Global cries about getting Zucked, or having one's personal information hijacked online, lasted for months.

Those cries have since ebbed, but E. Zuckerberg is still notorious. And he's likely to only get more notorious now that The Social Network has opened in theaters.

For S. Zuckerberg, this is a problem. A doppelganger sort of problem.

Already, his office in downtown Indianapolis gets about a dozen phone calls a day from people complaining about Facebook and demanding tech support. He gets about 500 Facebook friend requests a day, many of them coming from people in other countries who don't speak English, so he couldn't explain his identity even if he wanted to.

S. Zuckerberg even looks like E. Zuckerberg, with curly reddish hair and an antsy, slightly geeky demeanor.

But most of all, S. Zuckerberg bemoans the loss of being the only Mark Zuckerberg of note on Google. A standout in his field of consumer bankruptcy law, with several awards and a schedule of national speaking gigs — Zucked by an upstart.

"I was always on the first page, always number one. No. 1. Now," S. Zuckerberg said with an irritated sigh, "I'm pages and pages back. This guy is killing me!"

He even has a website, http://iammarkzuckerberg.com, that tries to set the story straight. But it's probably a lost cause. Search engines thrive on new content to rank pages, and there are so many articles and blogs being written about E. Zuckerberg that S. Zuckerberg can't compete.

"I can't win," he said, "There's no way I can win."

In some ways, the bankruptcy lawyer saw this coming.

Years ago, just curious about who else had the name Mark Zuckerberg, he found him: Mark E. Zuckerberg.

"I remember typing in my name (online) and finding a website for him," S. Zuckerberg said. "He was in high school, and there was a picture of him laying on his bed. And I thought, 'Wow, there's another Mark Zuckerberg in the world.'."

A few years later while Googling himself again, he found E. Zuckerberg, but this time while at Harvard University. (That timeframe, incidentally, is the setting for The Social Network.)

Then Facebook came along for college students in 2004 and for the general public in 2006. Today, Mark E. Zuckerberg is almost a household name. And if it's not now, it probably will be after The Social Network.

S. Zuckerberg isn't looking forward to it.

"I would expect lots of people asking me to be their friends (on Facebook)," he said. "I would expect that to probably double."

S. Zuckerberg isn't a fan of Facebook. He swears it ruined his marriage. His divorce is final Friday. He says he joined only to communicate with people he couldn't communicate with in any other way.

But the value of the social network is undeniable, even for him.

The bankruptcy lawyer says he has nothing against his counterpart. In fact, he seems to admire E. Zuckerberg.

"He's made a change in the world, the way people meet and talk," he said. "I mean, it's a huge thing that he's done."

And S. Zuckerberg would be the first to admit that there are worse fates than being mixed up with a wealthy, famous Harvard dropout.

"I went to Vegas one time, and I called for reservations. They said, 'What's your name?' and I told them. And they said, 'Oh, we can get you right in, sir.' "

Now, who's getting Zucked?
