現在多數攻擊都來自電郵, 但難以完全防止用戶不小心開啟有害電郵,防毒軟件也不能及時制止這些連結,建議增加電郵過濾服務及類似Flashstart等DNS filtering服務將該些網站阻隔,避免用戶誤點。

大型活動利用科技溝通及發佈消息可以節省大量人力物力(口水),但如果反而為「不想見到這種情況」的人提供一個簡單既single point of failure,只要telegram斷線就是對活動造成某程度上的打擊了,所以應該反思及進行預防及後備佈處。我建議 Telegram 在香港設置服務,除了加快用家存取,在活動時如只容許香港IP存取應該大大降低被DDoS既影響,或者香港自己開發一個獨家APP?
