basically i need to check accounts from a .txt file in a user:pass format to see if they are still valid. i will provide the website the accounts are from when you get the job.
it needs to run off of proxies which will be pulled from a .txt file as well. i will provide the proxies.
if the accounts are logged into and valid they need to be placed in a new .txt file in the same user:pass format.
this needs to be coded in VB and be open source.
