Security of the forum in Jupiter X



I run a national website using Jupiter X and the forum plugin.

I cannot verify every users when they register because they are too many, so it leaves the door open to fake accounts.

Yet there is an option allowing me to verify everytime somebody wants to post a new subject, which is more appropriate to check if the questions asked are right, and if it is not a fake account.

The probleme is : it seems like when I activate this option, it doesnt allow the users anymore to suscribe to their “favorite” subjects to find out when they have an answer.

Does anyone have tips to get a forum safer without punishing the users by activating a lot of restrictions ?
