Newbies are not such a target for account related hacks and crimes. Why waste time and money building your history, when reading and learning can be worth so much more?
Thats not true , there are many Newbie Accounts that get or got hacked as the mostly get into some things and downloading links where the magic happens.
And its the fastest and easy way for the hackers to get on some Accounts.
The Hackers create new Accounts and catching others with there Shit , i have seen that so many times the last 4 to 8 years here.
Old accounts are harder to hack since older members of the forum tend to have much knowledge on how to protect their accounts and use other offline security features to keep the account safe and secured.
It depends if they still active or not and if they use now the 2FA feat. we got here on the Forum.
If they inactive i would say that the older Accounts mostly easier to hack or buy them as the real owner dosnt care anymore.
Always check when you deal with some User or try to get into a new Project posted here the history of that Account and stuff.
