i'm receiving this amounts is this a method to analyze and track bitcoin wallets or something similar?
One way to prevent being tracked, is by using coin control (this depends on your wallet) and manually choosing which inputs you use. As long as the dust input uses is on the same Bitcoin address, it doesn't help an attacker to track your addresses.
If however your wallet uses all small inputs automatically, odds are it links several of your addresses together.
If fees go up to just a few sat/byte, it will cost more to spend the dust than it's worth.
Some wallets allow locking unspent inputs, Bitcoin Core for instance gives this option:
Option > Wallet > Enable coin control features > OK
Send > Inputs > "right mouse" on an input > Lock unspent.
