Quassel IRC

I was connected to an IRC server.
Suddenly Quassel became super slow and i had high CPU usage.
Quassel became unusable and it freezes.
I killed Quassel using btop resource manager.
But when i run Quassel again, it's still unusable and it's frozen.
Quassel tray icon appears in KDE, but i cannot view the main window.
I had to uninstall Quassel, delete the config files, then reinstall it again.

Before Quassel freezes, i saw myself invited in many channels in the server i was connected to.
I think the admin attacked me using Mass Channel Invites, by forcing me into many channels, the UI had lots of processing and froze.
When i connect to the irc server via the browser, the admin does the same (or another, i am not sure) attack, i see lots of random ASCII characters filling my chat screen that freezes my browser tab.

How can i defend against these annoying spamming attacks ?

I am using Linux KDE Neon https://www.mykfcexperience.me

You're facing IRC "mass invite" and "text flood" attacks, overwhelming Quassel and your browser. To defend, first, utilize Quassel's built-in features to ignore the attacker. Most importantly, inform the IRC server administrator, as they can implement server-side flood limits and ban the attacker. For robust protection, consider using an IRC bouncer like ZNC or The Lounge, which filters floods before they reach your client and maintains a persistent connection. If issues persist, exploring alternative IRC clients with stronger flood protection like Irssi or WeeChat is also an option.
