I'm new to this bot stuff, but since I use to add comments on hi5 one by one by hand, I have found that you can only send one comment and after that you get an error message. I have read in your bugs section that the program has the same problem!
However I have found that if, before you post your comment, click on the 'send message' link but before you go to that page click the 'add comment' link, you can post as many comments as you like!
Until your account is frozen that is! but a few 100 a day is still feasible!
