I have been similar situation. some chaptcha sites writ that they found dublicate IP or they wrote they add me as scamr. and why? they block my IP. I talk about sites which pays 1000 or more.. sometimes, they wrote that 1000 satoshi sent your account, after that I chack my account and there not any satoshis. it seems, there are scammers as a captcha sites or there are scammer who changes the wallet address. who was in this situation?
you will get after claiming in faucet to check the address where it sended the bitcoin and you can check is that the same address of yours you have copied earlier or not. If it is changing that its better you install good antivirus and search for malware.
I have used to copy and paste my wallet address every time.. But there are this problem. I have so strong antivirus, total viewer 360 , it write me which sites or files are dangerous. it newer install virus programs.. I think, in captcha sites are scammers.. can you tell me how increase my satoshis. I want to start without spending money. if you have reliable captcha sites send me reffelers links
