'scikit-learn' is on the known-megaproject org list. These projects use auto-triage bots and established security disclosure channels. Unsolicited automated issues from Repobility would be perceived as AI-generated spam. For security findings, follow the project's SECURITY.md policy. For non-security findings, open a focused PR or community discussion instead.
Megaproject â high spam risk
Could not determine 'scikit-learn/scikit-learn' star count (GitHub API rate-limited or unreachable). When in doubt about repo size, prefer opening a focused PR or a discussion rather than an issue.

The button opens GitHubâs new-issue page in a new tab. You will see the title + body pre-filled â review, edit if you want, then click GitHubâs "Submit new issue" button. Repobility never posts anything on your behalf.

For real security findings on big repos: use the project's SECURITY.md or private advisory flow instead of a public issue.
