Disable ACM, Google Scholar, JSTOR

[koppor]

We cannot get the ACM fetcher working (#5804) nor the Google Scholar (#7075). JSTOR has a traffic limit. Thus, we disabled them.

• Change in CHANGELOG.md described (if applicable)
• Tests created for changes (if applicable)
• Manually tested changed features in running JabRef (always required)
• Screenshots added in PR description (for UI changes)
• Checked documentation: Is the information available and up to date? If not created an issue at https://github.com/JabRef/user-documentation/issues or, even better, submitted a pull request to the documentation repository.

Is the JSTOR fetcher working in principle, and only hits the quota limit after a certain amount of usages? How many per day?

Not on my machine. Not at Dominiks. Please execute the Web Search for yourself for a triple check 😅✌️ Tobias Diez <notifications@github.com> schrieb am Mi., 23. Dez. 2020, 15:43:

I remember that it worked a while ago. Maybe they require some cookies or whatever to be present.
Edit// They now also use Recaptcha. I tried some access with curl :(
