[Question] Can I archive the EA forum on the wayback machine (internet archive, archive.org) ?

There are some great information on this forum that seems to be available publicly (I can access it in an incognito chrome window) and I would like to increase the chances of this information surviving for a long time.

When I try saving a EA forum page it looks like it does not render correctly on the wayback machine. Ex: https://​​web.archive.org/​​web/​​20200624163706/​​https://​​forum.effectivealtruism.org/​​posts/​​8vfadjWWMDaZsqghq/​​long-term-investment-fund-at-founders-pledge

The https://​​lesswrong.com website seems to have the same issue .
I opened a github issue on LW’s repo since I assume it is an issue with the source code of LW.
