It is much more difficult to impose a Browsewrap agreement. A user could easily claim that they never read it and therefore disagreed. To make your terms of service enforceable, let your users click on an uncheck box next to a statement that says something similar to "I have read and agree with the terms of use." You should also insert a general clause describing any specific behavior that your users may not engage in when using your website or service. General restrictions include screening, spamming other users, and reverse engineering proprietary software. .
