It will depend on what tor exit node you're using: cloudflare is a provider who puts a proxy between users and your servers in order to prevent bots from connecting. If a tor exit node has a history of bot activity then it will be marked as possibly malicious by the cloudflare network and require you to fill in a captcha, which is a simple task which requires non-free javascript. You can see a similar effect without using tor if a computer on your network is part of a botnet, then your IP will be seen as spammy and you'll be forced to go through the captcha.
