At the time of your mention, I temporarily prohibited access to <a href=\"https://gnusocial.jp/\" title=\"https://gnusocial.jp/\" rel=\"nofollow noreferrer\" class=\"attachment\">gnusocial.jp</a> to avoid DoS attacks, so I failed to receive the notification. Since last night, the attack has been stopped by stopping new registrations on the site.<br />\n<br />\nThank you for your offer to cooperate. But for now, your feelings are enough.<br />\n<br />\nI'm not a security or web expert, so I need to educate myself. I don't have the knowledge, so I don't know what to specifically ask other people for help in this situation.<br />\n<br />\nSince GNU social has weak security functions, it needs to be strengthened. I will resume general registration when I can take measures.<br />\n<br />\nAlso, I don't want to accept donations or grants. As you can see, it's a decentralized social network, so we have to be independent.", "isLocal": true, "attachment": [ { "@context": "https://www.w3.org/ns/activitystreams", "type": "Document", "mediaType": "text/html; charset=UTF-8", "url": "https://gnusocial.jp/", "size": 0, "name": "gnusocial.jp" } ], "tag": [ { "@context": "https://www.w3.org/ns/activitystreams", "type": "Mention", "href": "https://mstdn.jp/users/Sujiyan", "name": "Sujiyan@mstdn.jp" } ], "inReplyTo": "https://mstdn.jp/users/Sujiyan/statuses/109579182921973417" }
