So, I checked out Cyberleads[1], and...this dude is just literally (and brazenly) selling a list of startup executives' emails without their permission or consent. Not sure if that's even legal, but it's definitely scummy, and I hate when I get cold (and frequently, also technically SPAM) emails like the ones this guys is enabling.

Here's a direct quote from the site[1]:

  Every day, we scour the web and find every single startup that just
  raised money. We collect information about these companies, like
  revenue, size, LinkedIn and Twitter profiles, CEO information,
  emails, and much more.

  We then further investigate, and verify manually every entry on the
  list. Every single data point is checked, every single email is
  verified. Manually. By a human.

Edit: added quotes.

The other project, GitGardener[1] is... not necessarily sketchy, but it's obviously designed to make your Github look "better" than it really is (not that the contribution chart matters for anything, but that seems like what the service is trying to convey).

It's pretty gross that someone is trying to monetize this. There's actually FOSS version that draws pixel art in your contribution history: https://github.com/gelstudios/gitfiti It's pretty funny, though it doesn't look like its actively maintained anymore. To quote from one of the issue threads:

What better way to demonstrate that the commit graph is a not an indicator of a profile's importance? Hopefully someone who sees gitifi style art in the graph will immediately realize that they should take it with a grain of salt, and instead read the code.
