Is it not bad to use free web hosting?

It’s up to you really.

The biggest argument against using free services is that the resources that they make available are normally severely limited and that they normally have no backup strategy at all – after all, you get what you pay for.

If you’re OK with that, and you can handle your own backups, and can understand that the server might be underpowered, and your site could go offline for a while (minutes up to days at a time) then sure, try free hosting. If you want something more reliable with proper support, find a better paid-for hosting plan.
