>URL圧縮サービスを使って、URLを短くしちゃうってのはダメ?
色々調べてみると、長いURLについては米国のディスカッションボードでもディスカッスされてい、ご紹介のURL圧縮サービス類似の
というのが紹介されていました。しかし、これは発信先が全く見当がつかないため問題が多いとの指摘がありました。
TinyURL is evil.
TinyURLs are opaque -- hiding their ultimate destination. This inconveniences users, and can result in unintended visits to untrusted sites, including potentially sites taking advantage of unpatched browser security problems.
Tiny URLs also introduce a dependency on an outside service that could go away or change, for your one URL or all URLs.
For one example, their terms of service say that TinyURLs used for spamming will be disabled. So if you send me a TinyURL I'd like to censor, I could then spam that TinyURL to enough places to generate complaints -- eventually breaking your URL.
Or the entire TinyURL service could break or change ownership. So not only are unsure where the single TinyURL you see will go today, or in the future -- there's the possibility that at some future date, every TinyURL ever usd, in email/bookmarks/web-forums/wikis/etc, will redirect to new spam sites.
Always avoid TinyURLs, or only use them alongside the full URL.
