Legit sites starting to block VPN users... now what?

I’ve been using SecureLine since November, and I’m starting to get errors from websites that say “forbidden due to abuse from this address” or “use of a VPN is forbidden at this site”. And I’m not talking about Netflix or other streaming sites, but banking sites, forums, gaming sites, things of that nature that aren’t geo-locked.

I’ve tried explaining to the site admins that I use a VPN to keep my own information secure from my ISP, not to get around their security (it doesn’t do that anyway) but they either don’t respond or reply with boilerplate “VPNs are only used by hackers and illegal downloaders”.

So now what do I do? If I have to constantly turn off my VPN to log in to sites I use every day, there’s no point in having it.

Unfortunately, i’m seeing cases like this being more common with Avast SecureLine. Sites blocking, spam attacks, and other cases using their IP addresses.
I have another VPN service as well (because Hulu is not blocked yet), and those issues does not happens while connected through their servers.

In SecureLine, my most used server is Berlin and the amount of sites blocking the IP addresses keeps getting higher every week.

I saw a lot of IP addresses coming from SecureLine blacklisted by CloudFlare.
