Vultr is an US company. The US ban on gambling without (US) license also explicitely applies to foreign servers owned by an US company.

In an ideal world yes. However what would work is having an IPv6 only container for WHMCS, then using Cloudflare to provide IPv4 access through their proxy.

So can the IPv6 be used in place of ipv4? I am planning to host three VMs on one server and one of them will be used for whmcs, another for cpanel and another for my personal VPN so I will need atleas

If you want/need a unique ID / username for a client use the WHMCS clientid along with some static text. Ex. MVPSUser43 for clientid 43.

You can code whmcs hook for clientadd and clientedit. Only choice to do it in whmcs. Either remove the space there or filter the spaces.

if I can't forbid users to put spaces in WHMCS, I losed my money(facepalm)

As @Jar said: WHMCS is encoded. You have to filter it in your module, unless that also is encoded.

if I can't forbid users to put spaces in WHMCS, I losed my money

really no way to filter it on whmcs side?

spaces in first name will cause fatal errors for my VNC connection integration. is there a method to forbid this?

iwStack/Prometeus (Italy) has light DDoS protection to my knowledge. Pricetag is €18 for 4GB RAM instance with 50GB SAN storage + €9 Windows license, basic DDoS protection is free of charge.

We generally do not allow outside licenses because most users are trying to use a non-SPLA license on a dedicated server, which would violate the license agreement with Microsoft.
