Do not share that wallet address with anyone, do not even use it to participate in bounty campaigns, airdrops or connect to trade on the DEX exchange. Only you know about its existence and should only store important assets in it. You will never have those junk token transfers again. I did so and it has worked so far.
In the way you mentioned, we can easily do it so that we can stop accepting dust coins again into our wallet, actually ignoring dust coins in wallet is fine as long as we never exchange them because I personally also received some dust coins in my wallet but I ignored it and so far I haven't encountered any asset loss issues.
