I been seeing that some people have been making spam alts and then thumbing up their games to get it on to top rated. Witch ends up on the Popular section.
I have also been seeing that some games have been attacked by being spammed thumbing down.
Eg. Rockport, City of Remmington™ - Roblox
Witch a few days ago has good thumbs up rating then suddenly has lots of thumbs down.
I think there should be a Limit of how meany thumbs Up/Downs you can have for each IP for a certain game.
Accounts require email confirmation
There are temporary email services
Accounts must exist for a certain period before thumbing, commenting, etc.
After said period, exploiters have a steady stream of accounts aging for use
Limit activity from each IP
Proxies
Require a CAPTCHA each time someone comments, thumbs up/down, etc.
Nobody wants to go through the trouble
Then maybe you are behaving as a robot!? I have no idea how that thing works but I never have to type out a captcha.[/quote]
It probably tracks mouse movement and such and the speed which you complete the forms. Generally it makes it easier for users, but the difficulty for bots is not really changed if not a bit more challenging.
When they created that they should’ve probably tracked the speed of which the bot inputs stuff onto the field.
It uses risk analysis. It tracks your mouse movements/keystrokes on the page that the captcha is located. If the risk is too high, it displays the old-fashioned captcha to verify if you’re a bot or not.
