getting comments removed doesn't automatically lead to suspension, but it depends on why they're getting removed. if it's just automod catching you for low karma or new account restrictions, those usually don't count against you.
but if mods are manually removing your stuff for rule violations, that's different. some subreddits will report repeat offenders to reddit admins, especially if you're getting removed for spam, harassment, or breaking site-wide rules.
check your messages to see if you're getting any warnings from mods or admin. if it's just "comment removed" with no explanation, it's probably automated. if you're getting actual warnings or temp bans from subreddits, then yeah you might be building up strikes.
also look at what you're posting - are you dropping links too much, posting the same content across multiple subs, or getting caught by keyword filters? reddit's really touchy about anything that looks like self-promotion or spam these days.
worst case, diversify your posting and engage more naturally with communities before dropping any promotional content. better to have one solid account than keep burning through new ones.
