According to betblocker.org:
Please remember that once the tool is activated you cannot remove the restrictions until your selected restriction length has expired.
Only they can tell you what that means.
Instead of circumventing the software, have you considered if there is an option to make your Facebook or YouTube interactions less impeded? Maybe you can provide feedback by contacting betblocker and see if they can work on helping you, and others, in similar situations.
In the meantime, you can investigate which packages you do have installed (
sudo apt list --installed or
sudo dpkg -l). You can use
grep to filter the output.
grep is CaSe SeNsItIvE by default.
sudo dpkg -l | grep bet
sudo dpkg -l | grep Bet
Once you find the name of the package, it can be removed with
sudo apt remove NAME
sudo dpkg -r NAME
If you cannot find any packages, you can look through the list, without using
grep, and see if you find any suspicious packages. Don't go removing random packages, but you may see something glaring. Double-check before you remove anything, and if you do, back everything up.
If you have the original package (
.deb), you can use
dpkg-deb to inspect the package file, which contains data such as the name, and files that it installs. I downloaded the latest, so it could be different:
$ dpkg-deb -f /tmp/bet-blocker_1.0.0_amd64.deb

Bet Blocker, blocks unwanted websites
$ sudo dpkg -r bet-blocker
As noted, you'll need to make adjustments to your
/etc/hosts in addition to removing the package.
