The best way would be avoiding using these platforms if possible, if your livelihood doesn't depends on them.
Those who use the platform can still use it safely. If you don't want to be harassed by scammers or unwanted messages, you simply need to avoid joining general groups like those offering airdrops or free trading signals.
If you use your account on the platform solely for your business, I think it is unlikely that scammers will target your account. We can only join groups or channels that we truly care about and need.
That's not always the case. Currently, I have two accounts. One is filled with channels related to cryoto and one is not, only my personal trusted contacts. And every scam messages I ever recieved was on that first account. As for the 2nd one, there isn't a single unsolicited msg. What I'm trying to convey here is that as long as you don't expose your account, (carefully choosing legit channel is irrelevant), you should be safe. But as soon as you join any channels related to crypto, expect messages from scammers. That's why I said, it's better if we stopped using it. or keep it absolutely private from general viewers.
