Blockchain.com wallet reputation is not good at all in bitcointalk but if you have a rep here to take all the cases about the issues and help them to resolve will be good idea and also can bring back the reputation.
The reputation is mainly bad because of (security) problems inherent to web wallets. I'd never use a web wallet for any serious amounts.
Security is another fact but blockchain Wallet itself full of bugs because I personally experienced it when received ethereum from one of my friend, I tried too many times to access the wallet and at last I did somehow which happened a year or more than ago. I can still see such kind if bugs with lot of issues like Authorization email, which is the one should be resolved.
