Dont really worry,
The chances might be 99/100 that it will happen to you over a 5year period.
But yes, there have been multiple reports of this, so far only seen this happening once on sythe, not so long ago.
Since this is very unlikely and very rare it can happen. But I think this really depends on the persons botting history, what kinda and how many blackmarks he got and on how many accounts on a different ip.
The best thing is to monitor the bots,
Also use trusted botting clients, you can pretty much find only safe botting software here on sythe, look in the stickies and you may find out. But you prob know already. Some bots dont have to be monitored, that depends on where you bot, if you imagine a place is safe to bot you can pretty much leave it running overnight, (but in any case, ip bon or no ip ban there is no recommendation to suicide bot longer then 48-72hours and its wise to create a different pattern after you suicided, a more humanly pattern of playing (think about 10hours a day) It really depends if youre flagged or not, during the event which is easy to recognize by the amount of randoms you'll receive.
Mining, runecrafting or fishing are imo safe skills to suicide bot.
And if you dont have a botting history, i cant seem to imagine any of your accounts are going to get banned soon, as long as you bot safely ofcourse.
