You can use services of promotions for telegram, reddit, twitter or other social media. For example
upvotes.io sell upvotes for Reddit
always need to contact the professionals of their business. I'm sure upvotes.io know how to work, and make all perfectly
I'm not familiar with upvotes.io but if that's what they do, buying upvotes on reddit? isn't that an unethical way of getting upvotes? You are just promoting an airdrop and I don't think there's a need for that service as well.
Social media is the right way to provide information about airdrops.
Everyone does have social media accounts at least and many of us are staying on it for hours so its a good one.
although maybe at this time airdrop is not an interesting thing.
People learn that many airdrops are scam today.
