You should use a different wallet because the wallet you are currently using is being targeted by scammers.
That actually not going to help, as scammers use automatic distribution scripts, every time address shows any kind of activity. I have bunch or wallets, which were never used in bounties, aidrops and whatever, and basically every 2-4 weeks I receive tokens and NFT there.
Message to everyone - once again, there are no free money in cryptocurrency. You get paid only when do something. Time of free money has gone with ICO era.
i think if an address have transactions in it it will be targeted by scammer, the scammer are just sending random NFT everywhere after all cost of creating NFT and sending it to everyone is not that expensive I guess.
thats why changing address won't help, just ignore it and youre fine.
