There are often some “fair use” paragraphs in their respective ToS that they could enforce and either terminate your account or request you to uprade to a higher tier product. Usually (not always) VPSs are overprovisioned, so when people start to fully utilize their rented machines theit whole business model goes belly-up.

Be careful with compute intensive tasks. Some providers don’t like when you actually utilize your rented hosts.
