hello, and welcome to EVE Online
yes, it happens also in high sec… Can be between sides in the war against each other… Also can be as suicide ganking operations at the gates in HS.
In high sec there is timers and i strongly suggest your to get an idea about these time frames i will snip some veryimportant details for you from EVE Uni web page 
if you would like to read whole mechanics and info source is here :
https://wiki.eveuniversity.org/CONCORD
There is NO CONCORD in low sec… low sec mechanics are different. There is only some sentry guns around stations and gates… but they can be tanked easy anything bigger than a frigate and even some very tanky frigates and can be easily manipulated by resetting the aggaro and warp back… I suggest you to join a PVP oriented corporation to learn these fine details…
Yes they use warp scrambles and warp disruptors… as well as bubbles in null-sec. it is not possible to drop warp bubbles in high sec and low sec. And yes there is some different methods to tackle this issue… Again you need to learn mechanics i would say for example… warp core stabilizers but these modules have strength values to destabilize warp scramble and disruptors… one destabilizer module and remove effect of 1 disruptor ( Warp disruptor strength 1 to to tackle destabliser 1 … but fail to disable one warp scramble ( warp scramble stenght is 2 ) depends on modules ect a lot. … and if there is a big fleet and you tackled by so many gankers… there is a very slim chance you have enough modules in your low slots… plus… you waste lot of low slots for a useless thing …
Other thing if you have time and if you can keep cool you can burn back to gate and take the gate back… since others already get a weapon timer they will not be allowed to activate gate next one minute gives you enough time to gtfo. Or if you are in low sec you can hold your cloak… see what they are doing if they are about jump or they stay and camp there then you can check your re-spawn point and your ships alignment and try to warp to a direction on the way of your ships head ( that at least save you from wasting seconds with alignment time before you reach out to warp speed which is #/¤ of your maximum speed… if you reach out that speed before you get tackled you are in warp…
there is some more things to do… actually, my all answers here might seem to you loads of info… but believe me… this is a froum post and im giving you some info pretty from the surface… all these mechanics need to be acknowledged groundly by all eve players …
EvE Online is extremely realistic gameplay. Thas what makes EVE online different than many other games out there… and that’s also the reason player base average age is around 30 years old… Acknowledging and handling this game requires definitely kind of maturation and understanding… Stealing cheating and all kind of things also happen in real life too. in Eve Online there is no moma or police or army to protect you everybody can get back on you… There is many other games you are going around with guns and “MURDERING PEOPLE” .this is a simulation world that some ethical values are undermined … It’s in the nature of the universe… Being part of it or against it is your choice…You don’t have to love it you don’t have to respect it… but you have to respect that in this simulation those behaviors are allowed as legit gameplay style … so you need to respect all different play styles you need to be able to separate these aspects… some players just approach this despise and turn their face instead of learning these and be aware …They are assuming this will keep them away from that kind of people… that’s wrong … that only makes them easy targets …
Best pressi you can give to gate campers after you lose your ship is… writing curses ■■■■-talking and write to local and mails full of hatred and bad words… When you do that you are not only giving them killmails but you also give them a permanent written thropy and proof of salt …
You need to learn how to keep it cool and give good fights or good gangs in local… learn the lesson and them moove on.
You can take this only from your perspective and tell and do whatever you want … but you need to consider there is 2 sides in this … what you are trying to do or show won’t reflect the way you have been wishing … you wont hurt them but just please them even more …
if you would like to talk in more detailed we can talk in-game and comms … more effective… and the best way is to learn these things in-game by playing with vets … Learning mechanics fittings tactics is not really enough to keep exist and enjoy this extremely complicated game…
I have tried to talk to you in game … i remember you …
I think… most important think i can tell you… more imprtant that your question up there you ask…
first you need to be flexible… not stagnant not stick on one or two criterias… and especially insignificat ones… that will ruin your game from the first minute… and please dont make decisions without having enough information … Thats your weakness…take this as ground feedback … you are judging and cutting connection with people who wants to help you truly… and pushing them to uphill in fact they have no neccesity to do that for you …
that makes you easy target for wrong people also…
wish you good luck o/
OKII?
I’m hooked.
