Offtopic but important to this topic to!
Yep good RU and some other country eastside of US ( Germany).
People to
Custommers to and so on.
No really every country has hackers spammers and co or using services out of every country for a while ago a lot of old php cms wordpress and co systems are abused all over the world fast changing ip's and boxes trying scripts on our boxes, so after block again other ip very quick from other old php box. ( did some looking up php 5.3x and php 5.4x mostly)
Not "dead" server where those came from but live normal ( to old php) websites servers with cms systems still in use and working, in Netherlands Germany and so on, calling some of those hosters to warn them uhu thet where very very unpolite. ( cr.ppy, sh.t, str.nt m.rde)
So blocking tld / country ip block for us makes only sense for those region which aren't using our services or products, or whom we don;t want to deliver while to much extra costs or work.
That kind of blocking also use less power while visitors scrapers, search engines from those country's aren't using our resources then!
TO all admins keep in mind if you're blocking country's , your custommers agreed and knowing which country's , if they want to do bussines with RU, CN whatever who are you to block their bussines?
For the most normal Servers ( not infrastructure and other important services as some high tech development and co) it aren't country's but mostly people and "criminals" who are trying to hack, spamm, phising and co out of every country sometimes even "good" friends or coworkers do.
The utopic world , is every admin / hoster keeps his/her/it server clean and uptodate, so those box can't used for such attacks to others!
And even if so they are nice to the ones pointing out the problems to them solving quick and so on!
So in EU they should have a law for that, if a box / ip is doing abuse / hackiing things should go ofline in one EU DATAbase keeping track, no need for whatever commercial payed lists, no noone can reach that boxes ip and the otherway arround, only after cleaning up a quick AI automatic procces to check and delete if clean out of that list.
I don;t like some BLACKlist where it is to hard to get off or even you have to for whitelist pay money????? ( Clean is clean so why) everyone can make a mistake sometimes, also your custommers this is human!
Oyea the worse "hackers" ofcourse are facebook amaz.n and such company's for your all privacy and co,
We don't like google trackers on our servers /websites even if the are doing "so much only good things" they promissed once.
