https://www.stop-russian-propaganda.com/ used to be a web site about over-loading Russian propaganda websites with requests from browsers, as well as harder sites to crack like MIL.RU and commercial sites.
It's good to have revived an old blog and published a page with that link just in case it helped.
Sites like stop-russian-propaganda probably made a very slight difference, specially to enemy web sites that weren't used to defending themselves with the likes of Cloudflare. There was probably a morale-reducing or morale-boosting effect to either side. Imagine if you work in IT and are asked to help defend a Russian web site against individual activists from all over the world. Wouldn't you think that it's time to emigrate?
https://www.uahelp.me/help/ is where I found the stop russian propaganda link with various ways that people can help - mainly adding money to what taxpayers in the UK have already contributed.
Another idea: tanks and military hardwire.
I don't understand why donor countries like the UK want to donate lots of reserves of equipment, but not the whole lot. The idea seems to be to keep essentials like recently-made tanks, but donate what we can spare like the previous model. I don't get this idea. What are the tanks for if not to stop Russia and China invading? Russia is already invading power lines on sea beds; it is already invading with assassins to kill people in Salisbury. Russia funds daft politicians, if I understand right, in order to make democracy fail. Russia and China will not stop at some treaty line like the Minsk agreement that said they would stop after Crimea. If they win, and win, and win, it is only a matter of time before they annexe the UK or countries so close that we have to be close to the buffer zone and ignore what they do while moving closer and closer. Finlandization used to be the jargon word.
I don't understand the argument the other way. Maybe I have missed it. Why would we not donate every single tank to Ukraine (or whatever other piece of hardware)? You cannot do much else with most of this hardware. You cannot hoover the carpet with it, or generate electricity for a town, or
