> BLU keeps their data secret and no reports go to officials.

This is wrong. Their database is live online and they submit reports and complaints for top offenders (along with other advocacy work)

Edit: I found this on BB's blog:

"You may have heard of another app that does something similar. We're different: the anonymized data you contribute will always be free and open to the community."

BLU's database is trivially accessible and full of years worth of reports. But even if it weren't, the creators of BB aren't going to get very far by casting shade on other advocacy projects trying to do good in this domain. It's a very bad look.
