Right now I can confidently say that most airdrops are useless and as long as you keep filling forms, you will always get email notifications for more airdrops, they never get tired. Best is to unsubscribe from some airdrop host platforms. Focus on other aspects of cryptocurrency please
nice suggestion buddy . yes your right . anyone can send anything on your mailbox , they can be a threat such as malwares , viruses or phishiing links but you must not wory if you think that an airdrop that you join is legit . i was joining a lot of airdrops before but luckily i dont get hacked or phished or infected by a virus because i know what im dealing with . suspicious and shady stuffs can be easily identified tho .
