[<...>I also noticed that if you want to get merits is to contribute on the forum by having sensible conversations without using a "Signature" because "Signature" implies selfish agendas. For this specific reason, I won't wear any signatures (after UBEX) to have better conversations and learn. This is only my point of view and would try to prove, DYOR, this is not a financial advice LOL
I would say that signature is not an issue in general; it is the posts content that matters. I mean the spam problem is due to people not being able to post decent content, incentivized by the signatures requirements in terms of number of posts per week. But the signature is more of a passive actor, and it is really up to the poster to create decent enough content.
So @matthewoz101 already did the same thing and according to statistics conducted by you (@DdmrDdmr), it is proven that signature has nothing to deal with this and it's a good news for me not taking the same mistake that could last for months. Now the question still lies on "How could I post better content", maybe I'd take more time to read and spend more time to make this forum my "chill" place rather than social media channels.
