ブラウザーがフェイクアラートに感染しました‼😱😭😭😭😭😭
危険が指摘されたことを認識しつつも、デッドリックを飛べなくしてたとしても放置し続ける意図が理解できない❗
そのリンクは二度と復活しないし、被害者が駆除に要した損害をあなたは保証しないのだから😥

私の頭がおかしい❓酷い❗被害を被った上に侮辱された😥
そんなサイト言われなくても二度と行かない😒

万が一感染しちゃったらこれを参考に駆除すれば特に問題はありません🤤 → このページの codegist.net に飛ばないでくださいね🧟 なんか呪われています😅💦 / Twitter

遅いSDカードの時代は終わったのですねぇ😅💦SD ExpressでPCI Express(PCIe)仕様をベースに、NVMe Express(NVMe)プロトコルを利用とかも言われていますねぇ🤔 / Twitter
あれ❓TermさんのCrystalDiskMarkのデータが無い😭 / Twitter
Linuxなら、わずか2200円税込でも快適なマシンがさらに数で勝負出来ちゃう🥰SDカードオーバークロックしますけど😅 / Twitter

このサイト面白いけど飛ばないでくださいね😉ちょっとフェイクアラートを踏みに出かけています🤤同じURLに飛んでいるのに毎回違うURLに転送されますけど、読売や朝日の複製ページみたいですねぇ😁http://codegist*net/snippet/python/decode_sd_cidpy_mttronc_python / Twitter
つまり、過去に人気でアクセス量の多かったドメインを、悪徳業者はドメインが再購入可能になったら買い付けて、リンクしているページを利用して広告や詐欺誘導に悪用しているから放置できないってことです🤔理解できるかなぁ🤔悪徳業者に利用されていることを...🤔 / Twitter
ちなみに、この文献のインターネットアーカイブは存在していませんねぇ🤔誰もが必要とするようなコードではないので... codegist*netのアーカイブは2019年くらいまで何個か... だから、このURLを保持しておく価値は何もない😅💦http://codegist*net/snippet/python/decode_sd_cidpy_mttronc_python / Twitter
