+				I have been made aware today (13 May 2026) that there has been a security breach on 6 May 2026 of the website. The following information have been
+				collected:
+			</p>
+
+			<ul className="list-disc list-inside indent-4 my-4">
+				<li>User IDs</li>
+				<li>Email addresses</li>
+				<li>Email verfication statuses</li>
+				<li>Avatar images</li>
+				<li>About Me descriptions</li>
+				<li>Profile creation dates</li>
+				<li>Profile update dates</li>
+				<li>Profile picture update dates</li>
+				<li>Amount of Miis you have liked</li>
+			</ul>
+
+			<p className="mb-2">
+				The only data that wouldn't normally be viewable is your email address (the same thing you would give to people to receive emails), everything else was
+				publicly viewable (such as on the profile pages). The code that caused this to happen has already been fixed.
+			</p>
+			<p>
+				As far as I'm aware, no other information have been collected. The breach has been notified to the Information Commissioner's Office. Please take care
+				when opening any suspicious emails. <strong>TomodachiShare does not send any emails.</strong> Please do not click on any suspicious links.
