Some air drops require you to have .1 ETH in your wallet....they say it is to avoid scams or spam. Is there any reason to be suspicious of this? Obviously i never give away my private key and I have a designated encrypted air drop ETH wallet (so I generally keep no ETH in it).

as long as you don't give your private key  . you can leave 0.1 eth on your mew address . there is no risks at all . 

just never give your private key to anybody

if they don't ask your private keys ,, there is no problem,,
and 0.1 ETH in your wallet is good to filter the cheater as long 0.1 of ETH is in the wallet 1 month before,,

It's understable that they ask for this as an requirement, because they want the wallets they send the tokens to to be active and really used by the person who request airdrop.

If they didn't request this, people would apply for the airdrop multiple times with different accounts, and this requirement slows things down.

As long as they don't ask for your private key, you are good.

they just want to make sure no bot can join the Airdrop.
and Few member can only join.
i'm guessing Dark Ripple airdrop.
just don't give your private key nothing will lose ..

Ditto what everyone else is saying about private keys.  Also, from time to time I have seen random tokens show up with no interaction on my part.  Apparently these tokens are airdropped and the total you get is based on the balance you hold. 

In fact, this is a good strategy, which can not only reduce the amount of fraud, but also allow your own currency to be dropped into the community. I think this method is totally OK and completely acceptable.

I have never encountered this method, but by looking at history wallet eth on txid or transactions in etherscans, some one can assure , that he is not scams . this is a blockchian advantage.

Well they can only read the balance and not steal your money since you haven't given any private keys. That is just to avoid excessive spamming of addresses just to participate in an airdrop.

In my opinion, i think it is an indication that they will be checking your account if its being used or active. They cannot alter your account unless you give them your private key. I think it is safe to enter and join those kinds of airdrops. Different airdrops have many different standards and rules to follow before receiving free tokens. One of this is being active and having 0.1 eth in your account means you are active and not a bot/spammer. Also they are monitoring your transactions i think. In addition, maybe they set this standards because some airdrops don't accept newly created accounts and having 0.1 and is a newbie surely is suspicious unless you have multiple accounts or someone donated a great amount of eth to you willingly.

This is a good way to filter out the cheaters but not 100% the best way to go.

Nothing is suspicious about this unless they didn't require you to give your private key. As long as the private key is safe, them you don't have to worry to anything. This is just their strategy to see if you're not a spam joiner of airdrops, they need a legit wallet for a legit owner of it.
