A new PLEX for GOOD campaign has been raised by CCP to help out the situation in Ukraine. You can now show you support by donating ingame PLEX to the cause which will then be converted by CCP and donated to the cause.
On behalf of our LinkNet community I have used all of our extra ISK and donated 10K units of PLEX worth of 30B to the cause.
