I am a newbie here, but I'll tell you this. My favorite signature so far is the following:
Yeah, just a blank line. This forum is sooo overloaded with signature ads, sometimes they can be very distracting. At first I even thought that I forgot to enable ad-blocking extension in Chrome. Now when I see a blank signature it's like a breath of fresh air. Maybe it's just me, but I prefer clean design without tons of banners with "BEST CRYPTO CASINO EVER" or "GET FREE BITCOINS NOW!!11" titles thrown at your face.
Yeah i can understand that you don't like signature banners which looks so much eye catchy and colourful. Yeah i beleive that every person haven't got simillar tastes.
As an example you like clean design where other person loves bold colourful design.
