Will you advertise my business/product/site on your site?

I don’t normally accept requests for advertising other businesses/personal sites or products, unless I’ve already had some experience with said businesses/products/persons. I also do not accept offers of payment for me to advertise, unless I’m doing it through a reputable source/company or, again, I’ve had some experience with such said persons or businesses.
So if you, just out of the blue, contact me to advertise on my site(s) for your business or whatnot, and I don’t know you or your business (especially, if you don’t even mention what the site/business is about), it will be viewed as spam or potential phishing scam, etc. As such, I may or may not even reply to you. So no, I will not post a link/text on my site for you (even if it’s just a minor, little code). Most of my current “advertising” are either link exchanges with folks/places that I know or are places that I’ve had some experience with.
I’m sorry for any inconveniences this may cause and I’m honored that you want me to promote you, but I’m only one person running everything and do not have time nor patience to try and figure out if it’s legit or a scam. When I’ve offered activities or the ability for visitors to communicate with each other either publicly or by memberships in the past, I’ve always had waaay too many people/bots that abuse that privilege and I just don’t want to deal with that again. Also, I really don’t want my sites to start looking like a lot of sites I see these days, that are cluttered with advertisements.

I apologize for the inconvenience and I thank you for your patience.
