on threaded mode - not linear mode. Locking one particular chain or branch.
example:
first replay to a thread
Then add the fake lock
Just by clicking dont allow replay and thats all
so how this work?
O = you are still able to replay to this user
x = you are unable able to replay to this user
new thread - O
- replay - X
- replay with fake lock - X
new thread - X
- replay with fake lock - X
