This board runs 24/7 and although Redshift tries to keep out spammers and keep this place family friendly, some spammers are bound to creep in.
You may have seen it.
Many of the people who use this forum are as young as 12 and some of them are as young as 9 years old.
So seeing anything that you yourself wouldn't want a nine or twelve year old to see is unwelcome.
How can you prevent that?
