I even decided to make the investment of buying the domain name
That's disappointing to say the least. It's not even a website, only a domain forwarder.
What you could (and should) have done, is create your own website that presents the viewer with 3 addresses (1.., 3.. and bc1q..), each generated on the fly and shown only once. That would give each user a unique address to "dispose" of dust, instead of making it very obvious they're using a certain address.
If you'd then add the promise to wait anywhere between 1 and 5 years before moving any of the dust inputs, and promise to only use a random selection of inputs each time, you could actually provide a useful service for getting rid of unwanted dust.
I've thought about creating such a service myself, but decided it's not worth it as barely anyone would use it.
For privacy, it's better to avoid dust. Or burn it. Or add it to an existing transaction from the same address when fees are low. Or freeze the input in your wallet so you never move it.
So basically you are asking people for donations!
That's another reason one shouldn't offer such a service.
what is exactly the problem in having low ammounts of coin in a wallet adress?
The problem is that if you want to spend those low amounts you are going to pay a lot of money in fees.
When fees were high, I've seen many transactions with inputs that weren't even worth the fee it costs to add them. As long as the Max button in for instance Electrum maximizes the input instead of the output, people keep wasting money on fees to move dust.
It is a dust address, not a burn address. I think that you've made a confusion.
Here you go

I really like your idea about creating an actual website for this and Id be happy to have the domain I've bought for the next 10 years to be the website address. PM me and we can work it out, I'm not looking for money or donations. I'm going to use your 1BURNbitcoinBURNbitcoinBURP3vqZJo as the burn address since its one of those addresses without a private key for sure. I think it being a vanity address caused people to feel worrisome that I'd end up spending the bitcoins.
