Virtual chat world with cute avatars is inappropriate for tweens and under.
I had multiple accounts on Habbo Hotel when I was younger, and I can tell you from experience that children are better off with other virtual chat worlds such as Club Penguin. With that being said, for teenagers I would recommend Habbo over IMVU any day. Habbo Hotel gives users the option of customizing their cutesy, pixelated avatars with an array of clothing and hairstyles. They then head into the world of Habbo Hotel, where they can chat, dance, and participate in cool events and hilarious competitions. Users can either visit public chat rooms or private rooms created by other Habbo users. The public chat rooms, from my knowledge, are moderated. Private chat rooms are run by the users themselves. They have the right to ban or boot you from their room for no apparent reason, which is what happens way too often in Habbo Hotel. If they simply don't like the way your avatar looks, or if you're not a paid VIP member, you will surely encounter situations like this at one point or another. Private rooms are themed after restaurants, bars, shopping centres, nail salons, and hospitals, and users tend to roleplay. I am pretty certain that the language is filtered, so the major swears are translated into "bobba," but users will find ways to work around the filter. (Also, I may be wrong but I think there is an option to remove the filter anyways). Just like in any virtual world, you will find friendly people to chat with, and especially in Habbo since most users are in their early teens and are less likely to be crude and rude. However, there are still those users who will want to engage in sex chat by inviting you to their private room, or harrassing you by sending you numerous messages to your inbox. If I remember correctly, such users can be blocked or reported, but a lot of the complaints are not taken seriously which is upsetting. Privacy is always an issue when it comes to these sites, but if you don't reveal any personal information (and you are not forced to reveal much personal information when you sign up), then all will be good. The upside to Habbo Hotel is that it is 100% free to join, and there is nothing to download, as it is a browser-based experience. Therefore, there is no need to worry about potential viruses or malicious software being downloaded to your computer. Unfortunately, if you want to have access to more customization options and other priveleges, in addition to earning more gold coins, you have to be a paid member.
