It may depend on what Epictetus meant when he said he could still access Prosper's forum. One can see the main pages but cannot read the threads unless signed in. If he can sign in and read the threads, he must still be not be suspended entirely. If he can sign in, I wonder if he could make it through the first stages of bidding? I'd bet he could. In this particular case, I'm betting Prosper is being incompetent and deleting or hiding anyone's member page that contains forbidden links.
It is ver apparent when you are suspended. Immediately after logging in, you get the following prominent notice:
Account Suspended
Your Prosper account has been suspended. You will still be able to transfer any funds you may have out of your Prosper account and make payments on loans. However, any standing orders, scheduled transfers, or listings you may have created have been cancelled and your access to most other features will be limited. Please contact customer support if you have further questions.
And the above quote really doesn't do the notice justice. On Prosper, the text is all in red type, in a box with a yellow background, and the "Account Suspended" is in a large font. It is pretty much impossible to miss.
Clearly, Prosper cannot totally suspend the accounts of people when they still have funds in Prosper. That is an obvious misstatement. They'd be in legal difficulties if they did that. The most they can do is deny access to certain pages or links. They could remove the ability of a member to bid, etc., but they can't be suspending the accounts totally.
The email notification is written imprecisely. (That is no big surprise, is it?) They could suspend the ability to perform some functions; but as long as Prosper has funds that belongs to him, they cannot suspend his account totally.
It appears that there are 2 levels of Prosper suspensions. The most common (which I have, along with Cubbies, Lep, and others here), allows us to log in, check on our loans (except we cannot see extended credit data), intitiate transfers out, and read PM's. We cannot bid, transfer money in, or send PM's. I also cannot access Prosper's forums, although that might be a separate suspension, since I was banned from the old .com forums at the same time I was banned from Prosper.
There is also another level of suspension that applies to FAN and perhaps a few others. Under that type of suspension, apparently there is no access at all to Prosper.com; Prosper sets up an automatic bi-weekly transfer out of the lender's funds.
