Hello. In practice OVH block all client account / reseller / partner with any number of active service due to violation of one of the services.
partner has 10-100 active dedicated servers.
The servers used for virtualization, vps servers.
One of thousands of customers in the vps broke the rules (phishing). From a certain IP.
OVH blocks the whole account! Even if the problem resolved.
You can simply block 1IP, instead of the entire account.
If the violation is repeated several times, and the customer does not eliminate the problem, then you can block all account completely.
Actions can be triggered intentionally by competitors.
