On a forum like this where you have a big header and empty space on one side, I would place a leaderboard advertisement right there since it looks better than having a single ad between the header and forum.
I like having them in between posts sometimes as well
Discussion Hub :ROFLMAO:. There was a previous version of DH a very long time when I was younger which I ended up selling. That site didn't last long with the new owner who ended up merging it with another one of his forums.
We used to have ads on my forum but we removed them. As someone that uses an ad blocker on sites, it's just not as effective anymore to have ads. I don't like sites that block users and tell them to disable ad blockers.
I like using pre-made premium themes because they are well made and just cheaper to buy. I then like to customise the themes so it looks special and it's slightly harder to tell what pre-made theme was used.
Not sure what awards system we use over at DH actually but that, and the credits/shop system from DragonByte. In terms of the node icons, we just use CSS to add them.
I love the Spotify addon from ThemeHouse as well, fits in very well with a general discussion forum.
Just keep them in the banned user group forever since deleting them would create other problems such as allowing them to use their email again.
Just like Nous mentioned, just have a striker through their name.
The aspect of advertising. I'm not the best at the job and I don't like having to try and find new methods of advertising to improve the user base of my forum. Would love it if my forum would just magically get users lol
