I don't know if it is a SCAM but most of this share is SCAM. I know because I've joined some of them. You can try your luck with another place. For example, I discovered a funding project. I am sure that you hear Money Circle Rosca. AZ Fundchain uses this and I think has great potential. But they are running IEO yet. You may look at it. Their IEO already started on Stex.
Don't deal with SCAM airdrops in vain but instead invest in small, but beautiful projects. I am sure you will be happy with that.
i just checked the official twitter from Gnosis and found this tweet
https://twitter.com/gnosisPM/status/1126862975258845184and they said that they are not doing any airdrop at the moment, so that means this airdrop is just a scam
