[Scenario]

Avoid free hosting from pretty much anyone. Most of the time they are utterly unreliable and knowing some of the people at this community, they'll just take your .amx file and do what Mauzen said. Ban you, and keep running the same server w/o any updates. Even though it sounds stupid, it prevents them from having to set anything up for themselves.

Pay for hosting. It isn't that expensive and you save yourself a headache in the long run.
