Hi,
I have made a robot 2 weeks ago which fetchs and index'es rapidshare, megaupload and other free-upload websites download links into database table.
It runs automaticly each 5 hours and collect the links from about 20-30 websites.
In 2 weeks I have this:
100,000 links, indexed in mysql table.
The table takes 20MB of space
The table scheme is like this:

---

-- --------------------------------------------------------

--
-- Table structure for table `search`
--

CREATE TABLE IF NOT EXISTS `search` (
  `id` int(11) NOT NULL auto_increment,
  `time` int(10) default NULL, // the insertion time in unixtimestamp format
  `unique` varchar(255) collate utf8_unicode_ci default NULL, // the website unique file id
  `site` varchar(50) collate utf8_unicode_ci default NULL, // the website unique name
  `url` varchar(255) collate utf8_unicode_ci default NULL, // the file full url
  `filename` varchar(255) collate utf8_unicode_ci default NULL, // the filename, might be blank
  `snippet` varchar(255) collate utf8_unicode_ci default NULL, // the context, usually title, snippet from google search, description, etc
  `tags` varchar(255) collate utf8_unicode_ci default NULL, // tags like "porno", "gays", "hot chicks" etc, usually blank
  `password` varchar(255) collate utf8_unicode_ci default NULL, // if the robot found out there is password, this is where it saves it
  PRIMARY KEY  (`id`)
) ENGINE=MyISAM  DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci AUTO_INCREMENT=51048 ;

(the auto increment is kinda old because I fetched this information from an old txt file)


FAQ

Q: Are there any doubled links?
A: There are no double / duplicated links since the robot checks the database for duplicates before adding the links.

Q: Are there any removed (aka no-working) links?
A: There database has NOT been checked for not working links, but the links are from the latest 14 days, so personally, I don't think there are any not-working or removed links.

I even don't know how to quote this thing, so you can just come up with price tags and I may proceed with the sell (;
