I would add an image but apparently the sub doesn't allow it (or Reddit is being unhelpful to me). The usual volume of one-time contributions each month tends to be less than $1k. So roughly ~$70k was raised directly due to PHP2Shell.

You can see this by going to https://opencollective.com/phpfoundation#category-BUDGET and by adjusting the filters of the Contributions section. Set it to This Year and click the bar graph icon.

The reoccurring contributions also went up, but I'm not sure how to interpret that as it's down in November already. Maybe they are yearly contributions? Maybe the reoccurring contributions show up on the day of the month they are withdrawn and it's only Nov 2? Not sure.
