this is actually pretty easy... for setting up only 1 account with lots of connections, there is no need for a bot. you only need a bot if you want to add 1000+ contacts to a lot of accounts... i filled up like 30 accounts with ~850 connections manually... for each account you need about 5mins... actually there is a lazy solution too, which costs you 5$ - every active bhw member should know where to find that solution after reading 5$ (dont want to post link, pm me if you dont find it)...
so here's how i did it:
for my first account i paid somebody 5$ to add about 1000 connections/contacts to my linked in account. worked well.
so what now? now i exported my contacts as .csv, copied ONLY the email-adresses and put them into a .txt.
now you have to login to your fresh account without contacts, import your contacts (.txt file, importing .csv's dont work for me) - but now you only have the contacts, this is still not the CONNECTIONS. Now you have to go to contacts >> imported contacts, here you see a list of all your contacts sorted by alphabet. this is where a bot would be useful, cause now you have to click "a", then click "select all", then you have to click "b", then again "select all", "c", "select all" then you click "invite selected contacts". you see a notification "128 contacts invited" - after this you go on with "d", select all, and so on... maybe you can select all contacts with all beginning letters at once, never tried that. I always select all contacts from 3-5 letters (depending on amount) and then invite them before selecting more...
and thats really it - all contacts should be connections now (after some time).
Im sure if you use random people for this, they will get you banned. But as this was a list of a professional linkedin-connections-adder nothing can happen here...
there are also services for 5$ that will get you 1000 - 6000 connections... just think about where to get services for 5$...
without bhw i wouldnt be self-employed today (just to let you know how much bhw means to me), so of course im willing to give something back... lets say the first 10 bhw members sending me a pm will get my list (only 10, because i dont want to risk my list to become worthless, please understand)...
the rest will get the link where to buy a similar one for 5$...
good luck!
