First let me say welcome to the forums (I see this if your first post).
Second, I imagine Jagex is aware of this client (I've never heard of it though) and addressing it, as they've begun leaning more into enforcing official clients with the Jagex Launcher and Jagex Accounts.
I highly recommend not posting the link, as I'm not an expert on the forum rules, but I could see a link to a rule-breaking software qualifying as an "unsafe link." Or falling under a broader rule on advertising cheats. If Jagex needs the link you've provided here, they will likely reach out to you privately for it.

To any readers, I greatly advise you avoid this link and do not seek out this software. Unsupported clients can be malicious, steal your account/personal info, and can get you banned, regardless of how low they claim the ban rate is (A man looking to sell you a product will find a way to make you think you can't live without it). If you care about your time in this game, use the official Launcher.
Now with added
I've locked this as it's just giving a 3rd party site more advertising and spreading the word out there. I know you mean well as I and others can see by your comments but the best thing you can do is send an E-Mail to Jagex via their tipoff E-Mail address which is:- [email protected]
I've removed the title and opening post as you named a 3rd party client. Also posting their Discord. Bad idea as others will go check them out.
As others have said NO 3rd party software is 100% safe. They claim that so suckers will fall for it and pay them to use their software or scripts and they don't give a crap about peoples accounts once they get your money. Best thing is stay well away from them. Report to Jagex and let them take Legal Action against them throught the Courts.
As for You kicking your Clan Members who use it I think thats the right call. I would do the same thing if anyone in the Clan I'm in cheats in any way shape or form. Good call doing that.
I've locked this thread as nothing further can be done here. You have done your bit and the reports will be read by Jagex and they will do whats needed to protect their game.
