For me it was spam free enough before this rule... but it will save you a lot of work as you explained.
I strongly disagree that forums are only to talk. it might of been so 15 years ago, but definitely not now. Forums are for people with the same interest to share everything about their passion and now a days videos are a big part of it.
Thanks for your answers. Your volunteered moderator work is appreciated! I hope you find more of them and can again be more open to new/ not so active users. So far this forum is not for me then. Take care.
