My Bersa website got hacked in 2004 and then 2005 (I was informed
by the providers the attack originated in Malaysia). Buti na lang,
I had all reference files backed up on HDD's/CD's. Upload uli.
The discussion threads were permanently lost, though.
As for reasons "why"...
My marine macroalgal database got hacked in 2002.
No reason I can think of for anyone to do that --lumot 'yon, no?
I think most webmaster-victims are collaterals: iba yung actual
target ng hacker, na-damay lang ang marami.
I use free webhosting lang, which is really vulnerable to attack,
hence my multiple backup of files.
Ang advice ko lang, isn't technical in nature. Websites can generally
be clasified into two groups, "for-profit" and "non-profit". The
latter are mostly reference material or archives, and most are
describable as gratis services to the general public. Libre na nga,
e, so "consumer complaints" don't quite matter so much.
If you like your work, it doesn't matter whether the public feels
the same way. You can't please everyone, nor even know how
to please everyone.
Life is short, and your life is yours to spend.
Build/rebuild what is worthwhile to you.
If what you find worthwhile is a helpful service to others,
then perhaps it may be pleasing to God, as well.
