I don't IRC anyone or IM or any other chat. It is too risky in my estimation. Sorry, and thanks for the offer.
3 reasons why this estimation should be reconsidered:
First I like to make some things clear.
"Risk" in this context is limitted to:
- Finding out your external IP address and trying to access your network/computer ressources
- Exploitation of a security risk of a chat client installed on your computer
- Social engineering and exploitation of low education and/or weak mindset
"Chat" means real-time textmessaging, being a combination of a phone call and email, used as primary means of communication for instance in PlaneShift (the game).
"pm" means "private message" which comes down to leaving a message for another forum user, being stored on the same server and displayed in a similar way as forum posts, but only visible to the recipient.
"IRC" means "internet relay chat" which is a specific communication protocol to relay chat messages from one user(-client) over several interconnected servers to another user(-client) or a group of users.
1. IRC is a well-tested and comparing to the development of the internet a very old protocol (according to wikipedia established 1988) used in many applications. If you are interested in learning on how it works, check
the original memo to the internet community.
PS is using Freenode for IRC services. Freenode is a suborganisation of the nonprofit-organisation Peer-Directed Projects Center and is administered by volunteers. The network is set up with the purpose to provide FOSS projects a base for communication.
By using IRC on freenode you reveal your IP address to administrators of the network. To hide your IP from common users you easily can set up a cloak. However, if this scares you, you should be aware that your IP address is visible to the admins of these forums, to GMs and devs if you play PS, to any host of homepages you may visit.
Since you should have
no open services or network ressources either way, revealing your public IP to anyone is a neglectible risk.
2. It is not mandatory to use an IRC client installed on your computer like mIRC, which is a well-known and thoroughly tested client. You also can use clients that are web-based. This requires your webbrowser to be trustable and bugfree, which is even more questionable since it is a lot more complex than a simple IRC client (thus viewing any webpage would pose a bigger threat than using IRC over freenode).
3. Social engineering can happen anytime human communication takes place. The only way to protect yourself is education and the intelligence to avoid people who want to manipulate you. Since in this case the only reason you should have entered into communication using chat as means was to approach someone who could help you the time you need help.
As a PM may not be read immediately, chat may be preferable in this case.
If you still think chat using IRC over the freenode network is too risky, you should also reconsider the usage of MMORPGs and with this PS.
Last but not least I would like to point out that the said above mainly goes for forum PM and IRC using freenode as network. "Chat" as an obscure general term cannot be applied in discussing risks. For instance I would not recommend (if security is the primary priority) the usage of ICQ (because accounts are hacked and used by the internet mafia) or Skype (since they do not reveal their sourcecode and thus may pose security threats without users knowing, see Eric Raymond's essay The Cathedral and the Bazaar).
