It's pretty much the same for me when I'm browsing on my phone – ads everywhere! It's especially annoying when they break up the text, and you lose your spot.
I guess the reason for all these ads is pretty straightforward – forums need to make money somehow. Hosting a website isn't free, and ads are one of the easiest ways for them to generate revenue. It's a bit of a necessary evil, I suppose.
On a side note, I've been exploring digital marketing a bit and came across
AdSpy software. It's fascinating to see how ads are targeted and the strategies behind them. It's a useful tool if you're curious about the behind-the-scenes of online advertising or if you're in the marketing field.
