Obviously it doesn't apply to everything. But for something like a public website or mobile app that would be reasonably expected to be easily findable, the fact that it isn't is weird. One project like that makes me wonder what the situation is; several make me suspicious.

For what it's worth, some Googling turned up these links:

https://github.com/mochja/odovzdaj.to

but it shouldn't have been so difficult to find them.
