Blocking spammers from logging in without activation

[itmanager8815]

awaiting activation user can see thread content but cannot reply.
of course, posting privileges are set through group permissions.

forum admin panel >> users & groups >> groups >> Awaiting Activation >>
Forums and Posts (tab)

in Viewing Options there you can un-select "Can view board?" & save settings
that results in this set of error messages for awaiting activation group members

above setting may be also un-selected for guests group

Thank you.

This resolved my issue.
